doors and other parts wanted

[cheyenne10]

I am helping find some parts for 72 blazer. Need good rust free 72 doors, rear lift hatch (or can someone tell me if fiberglass is repairable on lower corners of hatch), full AC dash uncut (removed at spot welds). Also would be intereested to hear about rust repair on top corners of windshield frame.

The truck may need some good welding help. Are lower corners of doors repairable with bubbling rust showing or is it usually too late. (remember most guys are not as literate as efabman on sheetmetal repair). When repairing rusty rockers are truck replacement rockers used? (rocker boxes may be ok, do they need removed to decide)? Do rocker boxes just unbolt?

Also like the idea recently discussed on roll bars. In past I'm sure I've seen a 3 piece bolt together rear hoop that bolts to floor, did anyone find out if smittybuilt has this unit?

I'm not real familiar with blazers just trying to gatehr advise.
