Good question. I am looking at these for my 73 small block duster. Also,is there any problem running the super stocks on the street ? Or would the OEM HD 340 springs be a better choice ?
Just picked up a complete 8 3/4 741 with a sure grip and 3:23 gears for 375.00 (drum to drum) out of a 69 dart 340 car. Sounds like I did ok even if I have to replace the axles to get the large bolt pattern to fit my 73 duster.
