67 AIR pump spacer depth

[Mike E.]

Does anyone know the correct depth (length) for a 300HP, no AC, no power steering or brakes, AIR pump spacer for a 67?
Thanks,
Mike Ernst

The spacer used was GM #3890425. Mark Gorney successfully researched the size of all of the 66-67 AIR pulley spacers and posted it fairly recently. I wrote them down but I can't recall where now. You might want to e-mail him.

Mike, The info I got from Mark is as follows, GM# 3890427 is .339,GM# 3890423 is .497, GM#3890425 is .607. The last is for my 67 L79 with C-60. Mark has what the other 2 fit. I did not write them down as they did not apply. Dale
