"Ran into an issue when I realized I had a internal slave cylinder version of the NV4500. So I had to buy a new bearing retainer with a nose that the throwout bearing could ride on"

So you have a 96+ GM NV4500. What bearing retainer are you now using? What input shaft are you now using?

Sorry, I don't actually know. I just went to a mechanic that knows NV4500s and he just grabbed one and put my bearing race in it.
 
Mine is very close too. I was not going to lift it but I may have to.

Yeah. I'm going to cut away what I can out of the aluminum pan and TIG weld it. But I may also had a spacer to the bump stop. I'll be doing a bunch of measuring and calculation to make sure it never hits.
 
I added these extensions to mine. Note sure it will be enough though.

Sorry about the quality of these pics.. The one with the ruler is showing roughly 5" the end of the ruler is 8"

Did this mechanic install a standard Dodge input shaft into what looks like a GM NV4500?
 
Does anyone know the thread size on the brake lines for the front axle?

I need to know for the female end of the rubber brake line hose that attaches from the dust cover on the rotor to the axle itself.

We never changed out the input shaft

Then if you are using the original Quickdraw R2.8/NV4500 bellhousing kit, you are going to have a problem--your input shaft will be 1" too short. Notice how little clutch splines are showing past the new Dodge bearing retainer snout. Also, the GM pilot tip has a .59" diameter--the standard Dodge (fits the pilot bearing in the kit) has a .75" diameter. GM input shafts are 6.5" long--Dodge input shafts are 7.5" long. The original Quickdraw bellhousing is designed to use a standard (not diesel/heavy duty) Dodge NV4500.

s***... I told Chad (quick draw) what I was using. Also maybe I'm just getting a little connection with the clutch because I can't spin the transmission when it's in gear. Also I could've sworn the input shaft is getting to the pilot bearing in the flywheel.
 
I know that Chad was working on the shorter, GM version, but I don't think it ever went into production. Ask him for a picture of the depth measurement of the original bellhousing and compare yours. I went through all this with my project. There are so many variations of the NV4500 that you can't keep them straight. There is a third, heavy duty GM version that you can't even find in the books that makes it even more fun--I know because I put one behind a 4-53t.

Also, if your oil pan issues are only with the drive shaft (and not the yoke/flange or differential housing), consider using a high-strength, small diameter drive shaft.

Bellhousing measurements. Are people using the same size bellhousing from quickdraw?

Just wanted to post a couple pictures of the new dip stick in the aluminum oil pan. It fits in both sides
