Happy thanksgiving all.
To close this thread out (on my end at least) what i ended up doing is cutting down the pushrod that goes from zbar to clutch fork. Only the tip of the female half is threaded so i needed to weld a nut on after cutting, and also cut the stud down some as well. After some trial and error I got it to feel and work nicely and rest where it should. The kit i used did not come with a clutch pedal stop so I had to buy that separately.
Also for the firewall I used a hole saw in the dimple location discussed earlier in this thread and worked out perfectly. Rod is nice and center of the hole.
I was lucky enough to have an origin clutch fork that came with my used bell housing. I did not use the fork in the kit as it was the wrong one however i did steal the spring off of it. The throwout bearing i used came with my zoom clutch kit (10 spline from 63 vette) Shifter is a hurst competition plus for a 57 chevy and although it does clear the bench, it hit the dash in 1st and 3rd. I cut about 2” of straight at the bottom of the stick and welded it back together and it clears everything beautifully.
Also I am running a pair of hooker longtubes and the linkage will hit the #5 primary (goes up and over then down behind #7) I cut this out and routed it between the #3 and #7 primary and all is well.
There is probably more I am forgetting but that is the gist of it. Hope this helps.
