i recently purchased a used set of aftermarket a-arms for my 88. I tore it down to inspect before installing it and found 2 problems which i need you guys help. first problem is the metal cone spacers between the heim joints on the upper arms are worn bad and need replacing. second problem is the lower arms use a steel tube which ride on bushings at each ends AND a caged needle bearing in the middle portion which happen to have exploded. does anyone know where i can acquire a new set (total of 4) bearings and the metal cone spacers (total of 8). The caged needle bearing spec is OD=1.00 inch ID=0.75 inch.

P.S. i have been in search of these aggressively for weeks to no avail. Closest one i've found was Housers but it was .125 inch short on both OD and ID. Need help please.
