I need some help from the experts on narrowing down the vehicle that my drivetrain swap came from. The PO performed the swap forever ago and I never got the backstory on it's true origin. The drivetrain is in an 81 CJ-7 and I've been happy with it for many years.
What I know:
1969 Buick V8 - 350 Dauntless - T18 4 speed transmission and Dana 20 T-Case
What I think:
Based on what I can gather this was originally in a Wagoneer or Gladiator. I'm not sure if that means it could also be in a JXXXX truck either.
The engine was time for a rebuild and I am trying to tackle several loose ends that have bugged me for many years.
Loose Ends:
1.Clutch Pilot Bearing - Can anyone help me with a part number for this? I've tried searching for both Jeep and Buick models, but am not having any consistent luck here.
2. Throw-Out Bearing - If anyone has a part number handy it would be great. I found a N1489 on the center force site, but am not sure about it.
3. Clutch fork Boot - I've never been able to find a replacement for this. Anyone know of a source or good solution for this. I live in Colorado where it's super dusty, so trying to protect it more.
4. Bellhousing Inspection Cover - I've never seen a replacement available for purchase. I rigged up a homemade one on my own but it's not the greatest. I'll attach a picture of what I'm working with.
5. Reverse Backup switch - My guess is that the original vehicle had a switch that mounted into the first port on the back of the tranny cover. Mine has always had a wooden dowel pin jammed in there.

Hopefully there weren't too many questions listed above and someone will read the post and lend a hand. I'm a huge Jeep fan and one day hope to have a truck too!
Rock on!
