Is this a decent deal? 8.75 rear end

http://dallas.craigslist.org/dal/pts/2964122687.html

Hello all....love this forum! Been scouring it daily. I'm new to mopar and recently picked up a 72 dart swinger.

I want a 8.25 or 8.75 rear end. Found this 8.75 locally on CL. It'll need modding to fit my dart. Shortened tubes and new/cut and replied axles as well as spring perches relocated. (thanks to fabo I now know all that!!)

He's only asking 100 bucks. If he still has it....couldn't resist. I'm nowhere needing it rit now so I can always wait and hope for an a body rear.

You gents think this is worth jumping on?

Regards
