Paul, do you think my Cosmo cartrige will work with your design housing?
Bulent

Yes I do. Money back if it doesn't work.
What kind of plumbing do you want to use. I was thinking of equipping
them all with 1-1/2 hose barbs on the outlet and 1-3/4 hose barbs
on the inlet. What size hose fittings do you have on your rads?

         You are aware that the 86-88 and 89-91 pump cartridges have different
 mounting bolt patterns I presume. The 86-88 has 7 polts, the 89-91 (also 13B
 and 20B Cosmo) have 8 bolts. Just for the groups information. Will your pump
 casting be drilled for one or both pattterns?

Right Kelly. You will have to use the seven bolt cartridge.
It will be drilled for six of the seven bolts. I don't use
or need the one on the far right.
