When I got mine together, I took it to a local shop that often does race cars. They dialed in a lot of extra caster in my case. Look for a shop like that.
I worked at a couple shops like that. We did tons of classics/race cars/specialty cars. Anyone who understands vehicle/suspension geometry should be able to make a car go straight and wear tires correctly. 90% of the time we never even looked at specs.
To many "techs" looking at computer screens hoping for the "green is good" when that likely won't happen with our old rides. They don't understand how caster/camber/toe, etc work.
We just put some QA1 uppers on my co-worker's 69 Bee......toe was the only thing that was "green" on the screen when we were done but that thing goes down the road VERY nice and it'll wear the fatties he has on the front just fine!
