....Hi Everyone, A couple of questions; #1) I have a '32 Ford that has what's called a 'Hot Rod' 9" Ford rear end in it with 31 spline axles, single track & 3.0 gears. It has the 3" diameter housing..... #2) I also have a 9" Nodular Iron center section with a spool that's set up for 35 spline axles & has the large bearings in it. The housing that this center section came out of measures 3 1/8".... #3) I would like to use my Nodular Iron center section {mentioned in #2} in my Hot Rod rear end with my 31 spline axles {mentioned in #1}. Will it fit??? I also want to add a True Track w/ lower gears.... THANKS, Bill
