I'm surprised they haven't updated the applications on those. Doug was in on the development on those headers and he didn't miss much. From what I remember, it was either the idler or pitman arm that got worrisome on the spool mount cars, but it's been a while and I could be misremembering.
Man he was fun to hang out with back in the day.
They went on with no real problems. Driver side slid right in. I had to trim a casting nub off the bellhousing on the passenger side. I had the front wheels up on risers (about 12”) and the engine lifted out of the mounts 1-2”.
