Question for all the smart people out there. I have the frame stripped bare, the IFS crossmember welded in and for ease of use I’d like to turn it into a roller for moving it in and out of my tiny garage. Is there a good guess at spring perch angle so I can get the rear axle in? That way I can determine where my shock mounting crossmember needs to be welded. I’d like to have all the welding done before powder coating. In case someone has done the same setup before I’m using a 10 bolt 8.5”, SBC, and a TH350 with parabolic springs and the axle mounted on top.
