I had a older beast tq that I ran till last year and got a new frame. Squaring up rear end was done with driveshaft level. Once square and ladder is free done with that. The rear rails raised up on the tq under the so my baseline blocks were only 3/4 inch in rear. 31/2 inch blocks in front. New car is built like a midget so I’m at 31/2 on front and 31/4 in rear
