This Wilwood 1" unit is a good option for master cylinder upgrade for the S30 z car, 510 and 620, 280zx
It requires 3 small modifications:
1. Drill out bolt holes one size larger.
2. Reuse your stock threaded hard line outlet fittings from your stock master cylinder 1973-1983 Z car (since stock Wilwood fittings are standard thread).
3. remove drum brake constant pressure valves from front and rear hard line outlets of the wilwood M/C.
280zx owner:this master cylinder will only work on a 1979-1981 280zx brake booster with vertical mounting holes!
Note: bleeder nipples can be moved to either side of the master cylinder body.
