Now that it dawned on me that they are both Densos it makes sense. Denso's internal regulator is universal into most of their lines. Only difference it the pigtail connection which is vehicle specific.
Here is photo of I took of Toyota and Dodge side by side.

I am laying by the pool on oasis of the seas somewhere between The Bahamas and Jamacia, and I find myself perusing the various Cummins swaps we all have going right now. This is an addiction.

"Fun day at sea". Thats what they called it when I was on a cruise.
 
My wife is a Beachbody coach, and this is a reward trip, so good to catchup with all our BB friends...but still need my mud fix. I am going to trying swapping the Toyota regulator first, if that doesn't work I will go external.
 
Found a few photos that I had on my phone. Out of town at the moment but I will try to remember to snap some of the clutch/brake pedal contraption when I get back home.

I am up to this point in my build now, do you know which slave cylinder was used? I have an entire dodge hydraulic system that I could cut and relate with the correct fitting, but am. Concerned about how I would need the system as there does not appear to be any bleeder. Does your slave have a bleed screw? Also. Did you have any issues with the bore size since mixing toyota master with dodge slave?

I found this clutch line that is meant for a TJ wrangler, looks like your setup, do you know if this is what was used in your build. I wouldn't be surprised to find the Jeep and dodge slave fittings to be the same.

I believe I have all dodge parts except the master cylinder, which I think is a 60 series. No idea on bleed screw. I will have to look when I get back in town mid week.

I can't find any dodge slaves that do not have hydraulic roll pin fittings. Seems that people that need to adapt dodge slave to masters that don't use roll pin fittings replace the existing roll pin fittings with roll pin to AN-3 adapters. What I am not yet sure about is if the roll pin fittings are mostly the same size and style.

As far as bleeding goes, I figured out that there is no need for a bleed screw, can use gravity with the master cap open to bleed the line and slave.

JDM 80 series master cylinder. dodge dakota slave, you'll have to lengthen the stroke length. Obviously, custom line and fittings between. That's my one good deed for the month.....

I just found an NV4500 slave from advanced auto parts that comes with a bleeder screw. I am going to use a russel roll pin to -3 AN adapter in the slave and then a flexible AN line to the frame, where I will adapt to M10×1.0 inverted flare and run hard line up to the master (I have the LHD 80 series master).

What is the deal with lengthening the stroke?

Won't work, the master isn't big enough. Like I said. Dakota.....................................

Have you tried using an NV4500 slave with an 80 series master or just assuming it won't work. Cimarron has been using a 60 series master with presumably an NV4500 slave successfully and I don't belive the 60 master is any larger than the 80.

No I'm just making this all up. Do whatever you want, you'll figure it out. Cimarron is using a JDM 80 series master and a dakota slave but what do I know???:cheers:

I don't know what you know, you don't have any threads or posts regarding the clutch hydraulics other that a for sale ad last year. How are you certain that Cim has a dakota slave?

I was able to find some info on pirate with people using dakota slaves on NV4500. I believe I read that the bore on the dakota slave is 13/16" and the OEM dakota master bore is 11/16". I am yet to confirm the bore size on the 80 Master, but I think it is 3/4". If that is true, then yes I beleive you are correct and the 80 master would by pushing slightly more volume than a dakota master.

Not trying to be a prick, just like to understand the why before I buy.

Not using a 80 series master. I am pretty sure it's a 60 series due to it not sitting perfectly flush with the firewall. I will have to look at the part number to confirm.

I looked at my part number list and couldn't find the slave info. Odds are this means I didn't buy it for the swap so maybe its not a NV4500 slave. I'm pretty OCD when it comes to logging part numbers. I will definitely do some investigating and see if I can read a part number on it when I get back home. I do know I am using 80 series clutch pedal components from Japan.
 
No interest in arguing. I'm doing you all a favor. LHD 80 series master, clutch pedal, brake pedal etc from Canada. NV3500 slave from a dakota. You'll just have to lengthen the stroke and have a custom line made. All the mounts are there. You'll have to drill a couple holes. It all looks very factory because it is.....this is what we call a trade secret.

Buy your parts from akello??? He's in Canada.
I have a JDM 80 master and LHD pedals, hot them from Dave Stedman. After your comments a few days ago I researched the dakota and agree the bore size (11/16) works much better with the 80 master with bore (3/4). I ordered up a dakota slave and parts I need for a custom line.

When you say lengthen the stroke, are you referring to how much of the 80 master stroke gets used? The master max stroke is 1 1/8", which is all was used, will translate to 1.3" stroke length at the slave (assuming the dakota slave has that much travel to work with).
 
If I remember or make time this afternoon I will look for part numbers on mine to see what it is. Since getting back in town I haven't had any garage time yet.

Thanks Cimarron.
Would you also be able to grab a snap of where your push rod attaches to your clutch pedal?

Unless I am not understanding some very basic fluid dynamic principals, the bore and stroke of a cylinder are fixed values, not variable and cannot be adjusted. The comment about lengthening the stroke, I assume can only refer to increasing the amount of the available stroke that actually gets used.

If for some reason the 80 pedals and master don't actually use all of the 80 masters available stroke, then I could see lowering the mounting point on the pedal slightly would result is more stoke being used. I'd be interested to see if your push rod is attached to th OEM hole on the clutch pedal, or if an additional hole has been drilled below it.
