Man is this getting out of hand and mixed up. :-)
Fred, my original post related simply to the quality of aftermarket
brand synchros in the kits Allen refered to. Somehow that has gotten off
into an issue of brass vs steel synchros. The two are not
interchangeable. If you have a steel synchro box (early Roadster stock
boxes and all early comp boxes) you must replace the worn parts with the
same style. If you have a brass synchro box (late Roadster, all 510s,
and all Zs - other than race cars running the early comp boxes) you must
replace the worn parts with parts for that style box. You can not mix
and match. The issue was not which was better, brass or steel. It was a
warning about substandard brass synchros being sold on the aftermarket,
especially in the kits Allen talked about. The Nissan brass synchros are
fine. Its a question of the quality of aftermarket replacement parts.
Now if we all want ot go off and discuss the virtues of brass vs
steel... No, never mind ;-)
