Only one vendor makes the molded pad and it's not very good. As a matter of fact, it's pretty poor. Too thin and the clips pop out for starters. #$@%$&*&%^*!!! The flat molded areas are not in the true postition. When used on a 1968 Camaro with 396 engine, the smog pulley digs into the hood pad.........nice. I tell people to buy the old pad that is not molded but looks more correct. I actually called the vendor who makes these a couple of years ago and told them about the problems and they didn't seem interested in correcting the issues.
I agree! I purchased a Molded pad in 2001, & you pay a premium and incur high shipping costs due to construction(No other option). When installed on my 68 w/born with 396 parts, the pad rubs the original air cleaner lid. This scratches the chrome. As a concerned customer and understanding the 'Your the only one with a problem' attitude of mfr's & vendors I felt like doing a little research on these pads. I had long trashed the original and installed the $35 resto pads that were the only choice in the 1980's. What I found as a reference was the Old issue of Camaro Enthusiast that had a series of great 1967 Camaro reference (Read ORIGINAL) photos. On page 5 they have a shot of an original Hood insulation pad. It was clear and you could make out details and depressions and spacial relationships of the contours & indentations.
The reproduction missed the air-cleaner recess by about 1/2" on the radius. Keeping in mind the Big block offset to the pass side. I assume the SB cars do not have this issue?,,,,,Therfore the rubbing occurs.
I prepared an bunch of documentation and sent the feedback to (Manufacture) R.E.M. Auto in PA.
Nothing but silence,,,,
Well my Fix is to Run a $25 Tiawann Lid and let her rip (I drvie mine & it does have its fair share of 1980's resto errors)and swap to the orig lid at a show.
No problems at all with there cowl ind hood version on my pace car,,,,he, he
Not a bash here,,,just a little feedback.
