So I have thrown in the towel on reworking an old stock Model A frame to my liking. Going to build from scratch. Doing RPU,mild 327,turbo 350,3;42 S10 rear,3 in dropped axle. My question is will 2x3x1/8 wall tubing be ok or should I up to 3/16 wall? I know a lot of you have built frames and need your wisdom! Thanks in advance,Bill.
