It varies a little per car. I'm going through all these scenarios right now, as well. What size rim are you going with? I believe Frank told me the 335 on a 12" rim has a section width of 13.5" and on an 11.5" rim it has a section width of 13.2". I've heard to trim anywhere from 1/4" to 1/2", but it's better to cut a little too much than not enough, of course...especially before paint. I have the same question. I have repro quarters, so the factory spot welds are history and it's hard to tell the plug weld after is has been ground.
My car measures 14-1/8" from the inner DSE tub to the quarter lip at the 12o'clock position.
