1968 Plymouth Barracuda

you should try the stock shackles, those long ones let the springs flatten out and lose the arc. id run air shocks before those things. just post up looking for feedback on cap , or do a search on fabo for cap products. there are plenty of posts to steer you clear. i have the espo springs in both of my cars, and i put them in 2 other cars for people, im a fan of them.
