Went with Heidt's lower front control arms as the frame had been modified for them when I got it. Very nice set up as it eliminates the struts. Used Carrera adjustable coilovers. The original front springs from Classic Roadster in 1995 were 500# (too stiff in my opinion for SB 351). I went with Eibach 450#.
CAUTION: When I used the Heidt's lower control arms (CA-103's), the mounting points on it for the front sway bar were narrower by 1" per side and, therefore, the sway bar would not set up properly. I modified the sway bar; however, it would have been easier to cut the mounting points off and reweld them to the control arm in the correct position.
