Clutch fork / adjustment rod / torque shaft....

The engine brackets are bolted to the insulators and the insulators are bolted to the frame; BUT
the hole into which the insulators go on the frame are slots, long ones, to allow you to spin the engine, to get the carb level from side to side.
However, you can only spin the engine on those slots, so, as one side goes down, the other goes up. If you need more up, then you gotta shim BOTH sides up off the K, for whatever height you need.

If you have shimmed a lot, then;
1) Before you close the hood, you gotta make sure the air-cleaner stud still clears, and after, that your air-cleaner still doesn't rub. and
2) that the fan doesn't rub on the shroud. I have a really big fan, lol

On mine, she was an original automatic car, so the apron did not have a ball-stud bracket welded on. So after I got the carb pad leveled, I put that bracket exactly where it needed to be, then welded it into place. Then shifted it laterally to get the inboard end clearance to the headers, then bent that end to get it bugged out, then permanently shimmed the outboard end into final position......... all the while keeping an eye on where the Downrod was
That was 25 years ago, and honestly, I don't remember it being that big deal, BUT, criminy, I was only 46 years old at that time, lol.
