Hi Slowpoke, not trying to beat a dead horse, looked at Helwig#34-377411: .373x.748x1.125; Repco #REP333: .375x.750x1.125; #REP387W same but 1.00 lg; #REP3508: 375x.787x.813; No prices on any.
Advance Carbon:#ACP006 .375x.750x1.125=$9.17
Advance Carbon:#ACP019 similar, shorter=$8.33
All these are close, on the high side so that they can be sanded to fit, unsure if lead position critical. Hope this helps as I don't like being held hostage to manufacturers'
ridiculous prices for a slightly "non-standard" part. Good luck!!
