Need a pump dated prior to 45th day of 1971,
seized or free doesn't matter also tower clamps 5/8 and 3/4" dated 3rd or 4th quarter of 1970.
Also looking for a 1971 Corvette Consumer Information pamphlet.
Thanks

Smog pump hoses use 1-1/4" clamps. I have one that's restored that has DCM stamped on it. The DCM clamps were not dated. So it would be correct for your car. The other clamps I have dated for your time frame will be 1 and 1/16 in with dates of 1/70 (2 available) , 4/70 [2 available)

I have one somewhere in a box of smog parts, from memory it is either off a 71 or 72 Corvette, since it had the vette-specific diverter valve. I’ll see if I can find it to check the date code, may take a while though. It did spin freely and had some hoses and wittek clamps too.

Found it sooner than I’d imagined; unfortunately it’s dated a year too late..... sorry.
