The shop did a good job on those axles. To shorten and cut new splines is a decent amount of machine work and the price seems right. The pictures would seem to indicate that the 6T70 w the LFX engine would use identical length swap axles. There are a few of these swaps in progress right now but from what I am reading they are complex and not easy to do.
