My Axels are too long, the rear end has been shortened to 53 inches, not sure why, But this is how my brother-inlaw purchased it. I have B body Axels which are 5/8 too long. Can I safely cut this much off without resplining them, they are tappered up too the spline, not enough too respline them. This is a street only car. If I have these cut down it will leave 3/4 of an inch of spline, is this enough?
