Why don't you contact Robert Paul in Yoder Colorado; a friend of mine was in need of a full set for his late 31 Roadster Open Cab PU. Paul filled his order, the shocks were all rebuilt, and the cost was reasonable.
I personally have had him rebuild 4 sets of original shocks and they don't leak and work correctly. He is very fimiliar with the Judging Standards.
