Been lurking for a while...reading ALOT...Rooman's and other's post are a wealth of info....but , after looking at the torsion adjustment thread below, I have to ask...where did they originally get the bars from??? I know VW bug's had a torsion front end , as well as some early mopars, but I would think both those would be wayy to stiff...are these home /scratch made by the chassis shops that built the frame, out of say 4140 or something similar??I am wanting to build my rail from scratch...everything possible...I have already secured a steering box, and have a pile of 4130, a SBC & Glide, 9" rear, that I am going to shorten & re spline the axles....trying to do this as old school all in the shop as possible..also I have the tools & experience required to fabricate the car ..Have been building motorcycle dirt track & RR chassis for years, and have also done quite a bit of fab on roundy round cars, and door slammers....have a pretty well appointed shop as well...just looking for some back ground as to where they started with the development of the cars parts wise, as I know most stuff was re-purposed to start with....Thanks in advance Shawn
