Sorry, Jeff; I don't have an up to date book on interchanges between spark plug brands, but any auto parts store will have such a list.

I've always found Champion to work better and last longer than Autolite.

That is a Champion number. This is no longer a current number, although they do show up on eBay once in a = while. There are folks who specialize in NOS old spark plugs, so if you want = the exactly right plug, you'll need to deal with them. Otherwise, just use the Autolite 65, it is the recommended modern equivalent.
