Cant find the master cylinder I want

1986 dodge D100 manual brake 1 inch bore master. Make or get the adapter and then use a 1970 E-body brake rod or 71-72 B-body rod. Lines fit right on. My car stopped like it had power brakes. If using 4 wheel disc then use a 4 wheel drum brake proportioning valve. I had front disc rear drum and use a brass style 70-72 disc proportioning valve.
