Actually, there's an easier way, and one that still works after all these years of abuse at the hands of careless owners/mechanics: look on the outside of the fuel bowl.  There is a stamping there that indicates which version it is: http://blef.org/vw/t3/carbstamping.jpg

So my 1965 Variant has 26 and 27s, a 1966 should have 40 and 41, and 1967 should have 98 and 99.  There's more out there in terms of stamped numbers, but other than the 6V/12V versions, I've been unable to find out what the differences are.

Check out the following two pages from my factory service manual: http://blef.org/vw/t3/32pdsitchanges1.jpg http://blef.org/vw/t3/32pdsitchanges2.jpg

Since we're on the subject, if anyone has a pair of 26 and 27s, please send me a direct email.
