Do i jsut cut the pumpkin out and weld a new one in or what? i want to put a ford 9 inch under my car with the same gears, 3.73 and a posi.

ummmmmmmmmmmm no...

you have to pull the complete rear out of the car and put one back in.

if you pick up a 9" you might have to get it narrowed, then you have to weld brackets to the 9"
like the 10 bolt had.

Unless your making some serious HP, you would be better of staying GM and upgrading you 10 Bolt or going to a 12 bolt. Used GM and After-market Posi units are plentiful and reasonably priced. Stronger axles and gear/bearing sets are too. Going to a Ford 9" rear is an lot harder and MUCH more expensive. If you still feel you need the Big 9" get catalogs from Chassis Engineering., Strange Engineering, Currie Enterprises, PST for brake kits, and hang on! your looking at about $4,000. to $5,000. to do it right.. Hope this gives you something to go on.

Agreed. The Ford 9" is great, but getting everything hooked up in a mod like that is extensive. It is a very sizeable and intricate job not for the wary of heart. That's not saying don't do it, but plan ahead and know EVERYTHING that needs to be R/R and adjusted before diving into it. I also agree there are a lot of good mods for any GM that are less time consuming and less expensive.
