Smog Pump Pulley Spacer

[Peter S.]

I have a smog pump pulley spacer that is too deep for my '69 L46. The spacer measures 1 3/4" in diameter, but is 3/4" deep. Did the early C3s have different depth spacers, or did depths vary depending on the engine? This was advertised as a '68-'72 smog pump pulley spacer when I purchased it.

There were several different spacers used depending upon application and some applications used no spacer. The one for your application was 21/32" thick. All original spacers for 1969 were machined steel and not aluminum.

Joe,

Do you know what application used a 3/4" thick spacer?

Joe, as always, you have the answer. I was wondering about the smog pump spacer for my 1970 LT1. Do you happen to know the correct spacer thickness for that application?

Thanks.

As far as 68-72 Corvettes go, the 3/4" spacer was used for the following:

1968 with L-79

1971-72 LT-1
