    Can someone with a smog pump pulley measure the diameter for me? I am having a hard time finding the correct one for a 1978 308 and think I will have it made.
    This is on the pump side, not the cam side.

    Hi Chris,

    I'll have to look in the garage for mine. Are you just concerned with the pulley or the pump too?

    ONTH, I replaced mine with an electric unit. I think it was off of a Jag. You can search the forum for the thread. Nice thing with the electric one, is that you don't have to worry about the possible damage if the mechanical pump seizes.

    Thanks.
    I found an original at ICP... takes them a while to confirm though.
    Electric is an interesting solution, but I'm trying to finish mine up as original as possible before selling.

    It's a standard us part. Get one for a 1974 Jeep j10 pu with an amc 360. Ask me how I know. Pulley is 2.5 inches od lip to lip. There is a part that attaches to the pump for the hose you will need to fab.
