35 spline 9"

Seeing as my Toy is in the shop for a little while for susp and headers. I've got 28 spline axles on my early Bronco 9" with a lock-right. I'm looking at getting some 31 splined axles cut locally. Can a 35 spline be cut out of a full length 31. Also where would I look for 35 spline side gears for my Lock-right, if they work? I posted this on the Early Bronco forum to no responce. Would 35 spline axles be worth the effort, or should I just get some 31's seeing as the side gears would be more plentifull?
Thanks in advance PJL.
p.s. I'm about 4400 lbs soaking wet with 40"ish tires, and a 225 hp Ford 5.0, C-6, NP205

Stay with the 31 splines. Not worth the extra money to go to 35. With all of my hauling and racing on a 9" rear, I've only broken an axle once. It broke right after the splines but luckily the axle was still supported by the diff. bearings. Seeing that I had a Detroit locker in it I was able to make it home OK. Racing - I was running a 460 cid and 38x16x15 S. Swampers with no problems.

Did it go together nice and easy? You did something wrong.Will have to do it again.[img]/wwwthreads_images/icons/crazy.gif[/img]

Thanks, you've eased my mind, and probably cost.
