WIW '86 limited slip 3.73 w/ pics

[LEEVON]

This is not a sale ad, just need some guidance. I have been looking for a 3.73 rear end to replace my rediculously high geared 2.42 to compliment the 700r4 I'm getting ready to swap. Local yards want $250-400 for a 10 bolt open diff w/exchange. This is insane. I put an add on Craigslist this weekend and got a reply today. This guy has a 5 lug, 3.73 rear from an '86 and he'll take $150. And it is limited slip. He sent me some pics.

I know everybody loves to hate 10 bolts, but I really just want a stock replacement with the right gears. Any sugguestions on what to look for other than checking the ratio, abnormal wear, etc..? Also, is this a "gov-lock" or what type of limited slip? Would it be common for the axle tubes to get bent in a roll-over? Could there be any issues with the drums fitting up?

I'm thinking this will be a good score if it works out
