Need info on buying a blazer

[chevytruckfan]

I have the opportunity to buy a 2wd jimmy. I would like to find out some info on the number of 2wd jimmys made in 72, and also areas to look out for. On my truck I know the ususal suspects like rockers, cab corners, etc., but what about the jimmys? What are some of the issues witht the fiberglass top/hatch? Also can a 67 front clip or 72 chevy grill fit on the jimmys? The seller is asking $5500 and I will try to post some pics later tonight so you can get a good idea if it is a good deal or not.
