Rear transition pan metal work, part 4 - dual exhaust reinforcement plates priming and installation
The pans come as uncoated metal that need a good cleaning. Child labor to the rescue! Wire brush attachment on a cordless drill is fine here.
If you look close, you see one of them has the big hole for the seat belt bracket bolt hogged out. I failed to make a proper measurement when I welded the bracket onto the floor pan. Oops. The smaller diagonal row of three holes is where the exhaust hanger support bracket is installed. In any case, the reinforcement pan will now fit well with the corresponding holes in the floor.
Now there is primer on all surfaces here - the floor and the both sides of these pans - so there will be no rusting due to trapped moisture later on. Six plug welds in each hold them to the floor. All this will get another coating of primer later, so this is where we stop for now.
