carried the 67 chevelle to the chassie builder. seems the anti-roll bar is not going to work out "YET". not enought room. going to have to go to rear coil overs to make room to get the anti-roll bar in. dont want to go with the type that goes through the trunk. he called QA-1. he thinks they make a rear coilover that uses the rear upper stock mounting bracket. my question is are the QA-1 the route to go? i see QA-1 make several different types. which one would be the better choice? Proma Star? alluma whatever? thanks Dave
