I was wondering what T4 parts, if any, will fit a T3.

not many.


ball joints and cups
shocks
assorted hardware screws nuts, etc.

the front spindles and c-hubs can be used if you drill out the hing pin to 1/8" but the geometry is different.

turnbuckles are mostly close and all of the trans rebuild parts minus diff rings should also fit, diff balls, thrust assembly, diff screw. bearings also as long as the T4 is the original (not t4.2, maybe t4.1?) later went to some metric stuff.

I believe you might be able to use the bones, but not sure. wheels I think also fit across the board.

Good to know. Are there parts from any other rigs that will fit it with minimal modding? Yokomo, Schumacher, Losi, ect...?

Yep, pretty much. Go to AE site and download the manuals for T3 and T4 series and compare part numbers and the parts pages for each vehicle. I bought a T4.1 and B4 for parts to use just the slippers and top shaft. That morphed into a complete T4.1 FT and a FTB4.2 instead of running the RC10T and B3 in my threads here. T4.2 uses metric bearings on diff gear, but the rest is metric and the Stealth parts haven't changed much if at all in the 30 years.
CVD CVA should be same lengths, original T looks same as the T4 bones I bought for a cheap price on AE site. So, should be same for T3.

If I remember correctly the T4 bones are not the same as the T3 ones. But if you use T4 hubs then the T4 bones work on your T3.
