Just now wrapping up the rough-in installation of a 97 Grand Am rack in my 69 Vette.
I won't have time to get back to it until this weekend. I will be running a pair of passenger side tie rods from the 97ish grand am. I can't start to bump steer test it until after those are in. Having to get lengthened adjuster bolts for the tie rods.
The new tie rod assembly will be coming from the center of the car (longest possible tie rod length). This should help reduce bump steer issues.
