Oops just seen that it is 25mm long? Why would they go that smaller? They must have bored out the centers deeper into each diff half. The 30mm's are barely long enough.
I want to use this with my existing design aluminum front diff that uses all Tamiya parts and the plastic rear ones.
I was going to make a production run of matched externally adjustable diffs front and rear and just anodize them black.
I guess I'll just have to get diff bolts made too. Why do I always have to re-engineer everything I own?
