30 spline 10 bolts have a weaker carrier, its not really worth swapping the parts between them. look for a 14 bolt SF if you are going to do anything, some of them will bolt right in and be way stronger than any 10 bolt

 

Unless I'm mistaken, you can swap just the axle and side gears. It looks like it'd work anyway.

 

it'll be faster and easier to just snag a 14B semifloater and put that it
downside is that they are all 6 or 8 lug....and you have 5lugs. but thatwould be the best bet. as for the wear 30spline carrier...a detroit locker will remedy that issue

 

Actually, some vans and 454SS have 5 lug 14SF's...i have only seen a few though, and never in a wrecking yard

 

Yeah, I did do a search before I posted anything and did look at the 14 bolt SF option, but I took a look around and I've only seen one and it's on my Dad's boss's 454SS. I figured I'd try beefing my 10 bolt as much as possible. I'm gonna have an automatic tranny with a vacuume secondary carb, plus it's light in the ass. I dont think I'll ever make it grab hard enough to snap a 10 bolt if it's beefed up.

I have a 12 bolt truck rear end that I saved from the scrap yard when we cleaned up around the shop at my work, but I dont want to have to worry about it fitting well. I'd have to narrow it, put new perches on it, and new shock mounts, as well as get a driveshaft made. I'd be all for it if I knew of a shop around here that will do it, but most places wont do it 'cause of the liability factor.

If anybody has any suggestions or anything. I'm open to just about anything. I can drive around on the old 10 bolt until I raise enough money to do it right. Just cant have any fun with the brand spankin new 383 in it that's supposed to have a lil over 400 hp.

 

keep lookin for a 14SF, when you find it rebuild it and throw it under there. do it while your 10 bolt still works

 

I found some good information out today. I went to pick up my buddy's L89 engine from his 'vette that he just had all machined. While I was there, I talked to the machinist, 'cause he's been around forever and he told me to go to this place called somthin' like Fred's Tractor Repair and Welding Service; that he might still do a rear-end now and then. I went and took an afternoon drive and found this place. It's way out in the boonies. When i finally found it, I saw all the tractors on the yard. And low and behold

, there's a rail car sitting right with the tractors being repaired, lol. There's also a huge sign that says "custom rear-ends" so, it looks like I'm gonna get him to chop down the 12 bolt I found and make it fit. Too bad they were closed or I'd give yall his estimate for work to see if it's fair.
