Okay.. I started the build yesterday from the diffs and now got some problems. I got the diffs ready, used the stock revo diffs inner gears (with sealings) for the fastlanes inner cups and fastlanes plategear.
But the problem is now when I attach the diff into the integys outer diffcase with the fastlanes pinion gear the diff won't spin freely. Am I doing something wrong here?
Edit:
Found that the plategear has scratched the outer diff case
