Thanks for the comments guys!
Nash-man: This car does not have a Toyota differential. I Installed a 8.75" unit out of a 1968 Big block Dodge Dart.
I don't want to be in 5th gear at the drag strip, I want to stay in 4th, and make 1st gear a little more useful.
Update:
I bought some new diff parts today! (For the 8 3/4 Mopar the car has under it)
-Detroit TruTrac helical differential carrier
-3.55 ratio Ring & Pinion for the 742 8.75" casting
-Bearings
-Seals
-Shims
-other random stuff I needed that you don't care about.
Around $875.00 Ouch..... but I need it or the car won't move
In the meantime, while I was trying to save some cash to buy those differential parts, I decided to do something about that horrid color of the interior.
The dye/paint is still wet in some of these pics, it looks much better when fully dry. Turned out great! I have many other pieces done as well, just no pics.
