After recently converting from a C4 to a T-5 in my '66 coupe, I was itching to put new gears in the rear of my car. Not having much of a budget to work with, I decided to try installing an 8.8 Explorer rearend with a 3.73 Traction-Lok differential. I realize this topic has been beat to death, but I just wanted to share my experience.
I figured that rebuilding my 8" with a new differential and 3.80 gears would cost at least $600. I managed to complete this conversion for around $345. This includes rebuilding the Traction-Lok, and buying an aluminum driveshaft and having it shortened. I didn't need a new driveshaft, but I thought it was cool. I have more time than money. I wish I had the cash to rebuild my 8" or buy a 9" housing made to fit my car, but I took the 8.8 route.
I found many Explorers in local junkyards which had 3.73 limited slip rearends. I bought one out of a 1992 Explorer with rear drum brakes for $100. I have found many with rear disc brakes, but I wanted to retain my 14" styled steel wheels, and I was concerned they would not clear the disc brake setup. Plus, I had recently rebuilt my rear drum brakes on my 8" rear, and I was hoping to re-use these on the 8.8. I have to give credit to the Mustang Steve forum for a lot of the information I got on this conversion.
The result: Overall I'm very happy with the conversion. It took longer to complete than I had hoped and was a lot of hard work, but I think I am more satified having done this myself rather than buying a new housing. Because one side of the Explorer housing is 3" longer than the other, I shortened the it 3" and used two of the shorter axles. I also modified my rear drum brakes a little and used them on the new rearend. Everything pretty much lined up. I didn't have to modify the emergency brake at all. The most difficult part of the project (aside from getting the axle tube out of the center section, shortening it 3", and pressing it back into the center) was making sure all of the bearings lined up after welding. It just took a long time, and I have little patience.
Please excuse my dirty fuel tank.
