Front A body suspension help please

What bumpstop stops? I don't want those short hard poly ones.
Yes you do. But you gotta get the ride height figured out first. And once you do, then if you change it, you will need a new alignment.
And I would either take it back to that earlier shop and tell them not to change your height cuz the obviously don't know chit about how to do that, and I would demand a free "adjustment", or I would just never go back there.
The reason you want the polys is cuz when you stuff your baby into a corner really hot, the chassis will settle on the stop, and then try to lift the other wheel off the ground, which with a 273 would likely be the first time ever,lol. But while it's trying to, it will corner like it's on rails,literally. Until you hit a bump or a hole, lol.
If you upgrade the T-bars, then at proper ride-height you will have a really hard time hitting the stops, and if your 235s have trouble sticking to the road, then you will be sliding long before you get on the stops; So, IMO it doesn't much matter what your stops are made of.
Before you go to the alignment shop, you need to set the car level from side to side, front and rear. This starts with rear springs. If one is soft, it will mess you up.
