anyone confirm this?

I'm no expert but I kept my 10 bolt (mainly b/c of cost) and put Richmond 3:73 gears in it. The guy that did my rebuild told me I was better off w/the 10 vs. the 12 b/c the truck 10 is stronger. He's been running a truck 10 bolt in his 81 Firebird drag car for years w/out any issues.
Nice build so far, keep at it. Can't wait to see how the dash is going to turn out.
