Yeah, those parts on the passenger side were a bit fiddly. The biggest challenge for me was getting to all of the places that needed welding. Some of them are waay up there, under the dash! I'm just not that flexible! Finding the one piece, stamped inner-to-outer cowl piece was a Godsend! It fit so much better than the welded up version! Now, for the driver side, I waited to buy the new inner-to-outer cowl piece until recently. Big Mistake! I bought my first one from Chev's of the 40's. Now, they've changed vendors and are supplying the welded up version instead of the single piece version. I ended up finding a single piece version from Raybuck. It looks similar to the first version I used on the passenger side, except the finish is different! That makes me think other things may be different. Once again, time will tell! Below is a compare and contrast between welded up and single piece. You be the judge!
