Did you buy the 1/8-to-Revo shaft adapters from Mike? If not, those are MetalMan-made as well

. But they are essientially the same thing as what Mike makes.
Unfortunately that center-front driveshaft is so large. If you remove the aluminum steering brace that the driveshaft rubs, you'll see that I cut that down about 1/8". Just wanted to add, that center-front driveshaft on there isn't actually stock, it's one from the wheels that I cut up to fit there, for the increased strength due to its larger diameter.
Vantage makes a set:

It retails for $35.99. You could ask them for the lengths of the driveshafts in the pic, to see if they would fit, or if they have any of a length that would fit the center-front.
