Can anyone tell me which four link siystem will work and is best for a 1958 chevy apache with a firebird rearend
Alston, Morrison, Speedway, or even Chassis Engineering (I think) have the four link setup. CE will have the best price if available. For street use get the bars with the polyurethane bushings, rather than Heim ends, so the road noise won't transfer up into the cabin. If your not into competitive racing you might consider the ladder bar setup because it's just as effective for rear windup prevention, settings are much simpler, and also looks cool. 4 links are great for suspension gurus to get the very most out of any track surface condition but are really just for looks and bragging rights for 90 percent of us that bolt them on and never change the settings.
