Found a local sheetmetal shop that will make new floors up for the Blazer & will even bend the steel to look like the ribbed style in the rear. The guy at the shop figures the stock stuff is probably only in the 24 -26 ga range. He can make up the floors out of 20 ga for me. Does that sound thick enough?? Should I get galvanized or black? The bed & complete underside will be sprayed with Rhinolining or Line-x or something after. Thanks again Brian 89KBlazer Build it Right or Don't build it at all!!
