Chassis
1972 Chevrolet Chevelle 5.7L (H) 3-spd (SM326)

I was asked to install a rear sway bar on the vehicle​.​Figured out quickly the rear lower trailing arms are on backwards​.​The holes for the sway bar where towards the front of the car​.​My question is when the arms are installed properly does the flanged side of the bushing face toward the inside the of the car or outside. They don't fit perfectly either way .They will need trimming Obviously they're after market repops.

I checked the manual I have and it doesn't matter which way they go. The bushings only fit one way so they have to be installed correctly. Just make sure to have the weight on the vehicle when you tighten the lower control arm bolts.

If you have the correct rear sway bar, the mounting holes should be toward the front on the inside​. ​Hold the barup to the rear end and you will see what I am taking about. It should have two bolt (mounting points) on each side. If the middle of the bat is straight, you have the wrong bar. The sway bar will form nicely around the bottom of the differential. Both my Chevelles had rear seat…

This is what the factory bar looks like; the image shows ut upside down. cdn3​.​volusion​.​com/vujmh​.​gadew/v… If they gave you a Hotchkiss kit the mounting will be different and the bar will mold around the back of the diff cover. Using a bushing on the axle and eye kinks at the front.
