Another rear end question

[belvedere 67]

As stated in my previous post I want to find different gears for the rear of my belvedere. I'm getting a 1967 barracuda parts car tomorrow. Dumb question but I should be able to take the 3rd member out of that and switch them.correct?

Are they both 8 3/4?

I didn't check. When I get it home tomorrow,I'll check. If there both 8 3/4,the swap should work,correct?

yes, if they're both 8 3/4, what motor did the parts car come with originally?

318 wideblock,i was crossing my fingers when I opened the hood I'd be looking at a 340.
