I figured out the ball joints needed to work with the Chevette spindles, the upper joint from a late 60’s GM midsize car (GTO’s and whatnot) works for the lower, and the outer tie rod from a late 60’s VW Beetle works as the upper joint. It was hard to find a lower joint that bolts in, and an upper joint that threads into the A-arms. The only majpr driveline parts I have to get now are the steering rack, (MG Midget will work) and a driveshaft.
