From what I've been told the B28 can has  been discontinued for some time. You will have to call around with the numbers supplied in this post to try to find one in stock somewhere.

Called around and cannot seem to find a B28 canister. My car has a B16 now and with Johns vacuum setup the car is a lot more streetable for cruising. Thanks all  Paul B

GM Parts Direct has them, I ran the number John posted and it's in stock. So does the other link I posted. So if you want one you can get one. Calling around will not prove successful. My supplier can't get one either.

Get the B28 if you can. They are ideal for High perf. low vac. engines.

They must have disappeared when the site was hacked - here they are again; this is the factory setup.

Here's the second photo of the "driving" setup, with the distributor vacuum advance line connected to the tee in the choke pull-off hose where the diverter valve signal hose was connected on the factory setup.

I did this setup on my 68 Z and I must say it was the best thing I have done for the car. It is crazy how much nicer the 302 is to drive just by changing the canister and doing Johns vacuum setup . It takes five minutes but what a improvement for the street.
