hello everyone. i was cleaning out my dads shed over the weekend and came across this box w/ smog stuff in it. don't know what it fits, or where he even got this stuff from, but he's had it for a log time. haven't done any research yet, just thought i would post here first and get more accurate information first. thanks. Jim

3925522 pulley is deep groove, 68 L78 and Z28 and also Corvette but don't know those years
3927116AU pulley stamped in an arc, don't know year that was done but probably 1970's
3927110AO pulley stamped straight, is the last number 0 or 6? Don't know AO code
3942533 diverter extension used 1969 and up. I think at some time the tapped holes changed size
Pump mounting bracket might be Corvette, check Ebay listings
Diverter valve should have a stamped part number on it on a flat spot where it bolts to the extension
Pump date 31381S is 1969, 313th day of 1968.
That's all I can help with. Looks like a mix. Martin
