A couple of things on the Cobra Restorers pipes. One, the Restorer headers need to be trimmed. We did this by installing the headers and sliding the the side pipes on. We would check the fit and remove the headers. We would trim a little at a time to make sure we didn't cut too much off, so this approach must be repeated several times (I think we did it 3 or 4 times) It tedious, but it works and to me it was worth the $600 as the Restorer pipes are less than $900 and the Kirkham suppilers wanted $1500. I understand the headers from the Kirkham suppliers come ready to use.
For the brackets, we used some heavy springs to connect the pipes and headers. This way the tabs don't need to be lined up perfectly. I spaced them about 2 in apart. I have no problems with leaks at the header/sidepipe interface. I had to go to the split lock header bolts to stop the bolts from backing off the exhaust port though.
I use the loose headers and slide on approach to get the headers on. That is hard enough. I can't even imagine trying to get them on any other way.
