Just purchased a TT-02 and some Hop Up parts.

I purchased these for the Front:
ITEM# 53792

RC UNIVERSAL SHAFT ASSEMBLY

However, I had also installed the

ITEM# 22047

RC FNT DIRECT COUPLING SET 39T

The Universal shafts are No where close to fitting. They are to long, and I'm unable to get the Hubs to attach to the Front Arms.

Likewise in the rear. Once I discovered they wouldn't fit up front, i tried them in the rear with the Oil Filled Diff. Still to long to really fit correctly. The universals went into place, but they were still long enough to compress my Diff to the point it wouldn't rotate freely, and would literally grind the gears when turning it manually.

I don't have much of any experience with Tamiya, has anyone run these combos, and what am i needing to replace to make these shafts fit properly?
