TC3 to TC4
Re Post 10824 on the previous page.
I finished the conversion of my TC3 to TC4 with Associated parts. I made a list of parts that you need in post 10824 on the previous page. Here are some additional items you might need as well as some additional items that are different on the TC4.
ASC 2230 TC4 front Body Posts, The old rear ones will work. The fronts too if you want to redrill them. They will be oversized in diameter though.
ASC 7874 and 6926. These are 5/8 and 7/16 inch Socket head capscrews for the motor mount clamp. The old motor mount clamp from the factory team kit will fit, but the new one lets the motor breathe a little better.
My Set of Hardware for the new steering links was short two bushings to work on the TC4 so you will need at least two more bearings or bushings 3/16 x 5/16.
The New TC4 has thicker input shaft cups for the diff, but they are not larger diameter. The new driveshaft thus has a smaller ball on the end. The old shaft will not fit the new cups or vice versa. If your shaft is the least bit damaged get a new shaft and use the newer cups.
New foam bumper ASC 31023. The hole spacing is different, but you might be able to make the old one work. I like the twin deck bumper, but it needs more protection on the sides.
The inner hinge pins and pivot blocks are a little beefier than the TC3.
Here is a pic.
