Last one. Ran a skim coat of body filler over everything because this side had been so twisted up. The structural stuff is all underneath and frankly with the extra welds probably stronger than factory. The skim coat just evens the joint out because someone had taken a 10# hammer to this in an attempt to straighten it (unsuccessfully) years ago

Thanks, very much appreciated. I’m no professional welder, I’ve got a total of zero certs, just a guy having fun in his garage 🤣
 
Making progress…

Got it to here and verified our rotors fit with the caliper configuration. Waiting on a few more parts but it’s much closer

Some things are just too WOW to keep to yourself. Probably should get submitted to the “worst upgrade to your 40” thread 🤣


This is the rear that originally was on the 40 we are doing, SOA at some point, mounts are gone now


IMG_1578.webp



By far, the wildest and poorest rear disc conversion I’ve come across. My guess is the rotors are ‘79-‘85 Toyota mini-truck. And the PO friggin’ WELDED them to the semi-float shafts!


IMG_1579.webp



Calipers are mounted on 1/2” thick flame cut brackets and what the calipers are from is anyone’s guess


IMG_1580.webp



Cracked the diff open. It’s got a Loc-Rite or similar lunchbox locker.

But the carrier center pin retention bolt? Broken and what appears to be repeatedly staked in place. So….. how was a guy supposed to EVER access a C-clip in order to pull a brake rotor/axle shaft combo? This stuff thrills me 🤮

Back, bottom side of the frame finally got some paint


IMG_1583.webp



Added two brake line tabs to the rear also

Thx! Just over a month into it now, going pretty well I think
 
Ya think? Going gang busters. Makes my 43 look like it's going backwards. I've got to lift my game......
lol! I’m hoping to have the rolling chassis complete end of February if all goes well. We’ll see. Should at least have the frame sitting on the finished axles next week if some additional parts come in.
 
Ah, the dreaded 'if some additional parts come in' scenario. That's why mine isn't running yet too. I'm waiting for the gear which goes on the new H55 output shaft to the new transfer case. I could use the old one off my current H55, but I want it to be all new. Looks line a late March delivery......

But now I can't get the idea of a receiver hitch in my rear cross member off my mind. So at least I've got more projects.
 
Exactly. This is how it goes. And it’s usually worth the wait for new parts and the ability to do it correctly, once, the 1st time
 
Oh…. The fiddly stuff that isn’t any fun but needs done. Made plates to fully box the underneath frame rails after the Saginaw kit was done. Essentially to extend the lower about 1.75” to match the other plates

So Ed asked me if I could fully weld the frame crossmember plate (inside the cutout) to prevent any water intrusion. Ummmm, sure. I’m down for bizarre out of the box welding that nobody else is doing 🤣 I’ll be able to finish the rest once the frame is back to “correct side up”

Oh what a TREAT

Pulled the engine off the stand and cleaned up the end of the crank with a wire wheel before taking all the measurements for the input bearing. Found this little bellhousing bolt stinker broken off in the block. Well below the block surface


IMG_1613.webp



Fired up the TIG. If you attempt something like this with MIG you’ll be welding yourself straight up a creek


IMG_1615.webp



Kept the weld only on the broken bolt, out it came, in pieces. No damage to the block threads


IMG_1614.webp
 
Took all the caliper measurements related to the transmission input shaft and bearing. Determined I’ll need to use the smaller bushing which goes deeper into the crank.

Measure, calculate, then put the trans on the back of the engine and verify. These are boroscope pics and the input bushing will be correct

I really need to clean the input shaft up 🤦‍♂️

Took a quick peek in a cylinder. Ed DID say it was .060 over 😂


IMG_1623.webp



Cylinder walls look great tho for a motor that’s sat for well over 2 decades


IMG_1624.webp


IMG_1625.webp
 
Well that’s much better


IMG_1626.webp



Clutch alignment tools. The plastic ones are “ok”, lopping the metal shaft off a junk trans is MUCH better and nails the alignment every time. This one is from an SM465


IMG_1627.webp



Fresh externally balanced flywheel, ARP fasteners and a new pilot bushing


IMG_1628.webp



Used pressure plate and disc. The disc still has factory lettering on both friction sides, stuff has just sat forever. Took a jitterbug sander with 220 and 400 grit to the pressure plate to dust the rust off


IMG_1629.webp



All done

A bit more progress, at least it rolls around. These are NOT the wheels that’ll get used

IMG_1631.webp



New intake, valve covers and we verified the carb sits right


IMG_1632.webp
 
Factory frame crossmember tube is out. Was going to weld caps on it but I think this looks good


IMG_1636.webp



IMG_1637.webp



Also finished welding and sanding the Saginaw crossmember plate


IMG_1638.webp
 
Aisin hub assembly


IMG_1639.webp



Done. Assembled with AeroShell grease, smooth as silk


IMG_1640.webp



Front rotors came in. Front axle is certainly a mix of stuff. ‘79-‘85 knuckle outers and birfield, ‘88 Landcruiser rotor, ‘91 4Runner calipers and pads.

Getting set up for engine placement. Think I’m going to need a set of fenders and aprons to verify where the body is actually going to land and maximize drivetrain space
