i can not see a using short a arms a problem. the spring rate mite need to be changed . it could ride hard but that is not to hard to fix .this is not as hard as trying to get a big block in the s 10 sub .i check my 50 chevy it is 70 1/2 rim to rim with the cam front sub with stock a arms with 5 inch rims .i can get shorter by cutting the back faces of the rim 70 so if you go with steel rims custom go for more off set you could go down to 69 or 69 1/2 easily
