What is the narrowest you can build the 8 inch? Im trying to get an idea of how much clearance i can gain for the rear wheels.

I could also use some recommendations for who to take the rear end to for this. I've noticed that 4-lug axles for the 8 inch don't seem to be available, so i imagine shortening up the rear end will not be easy or cheap. If anyone has experience with this project please let me know how things went.

I am in the market for a 4-lug 8 inch rear end in case anyone spots one!
