64 Valiant 360 Swap HELP.

I just had a thought.
You know that company,(I can never remember the name), that makes BB headers for A's where the one pipe goes through the apron? I wonder if they'd be willing to make a bunch for you early A guys with sbms . Maybe even to fit all the goodies like P/S and M/Ts. Even if 2 pipes had to go through the apron.
If those came out, I would step up my search for an early A. Specifically a nice roller-wagon. You know those are coming up to 50 years old or so,now.

I seem to recall the Schumacher mounts fudge with the engine height.
