I ran across this site for SU carbs. What is cool you can use the velocity stack inside the assembly.

They are primarily British SU carbs, but I don't that could matter would it?

I also found this sight that has SU assemblies for Harley-Davidsons. Don't know if they fit, but it would look pretty cool with "S.U." labeled on front the assembly.

In a similar vain, I found these guys in Sydney Australia:

They told me that: "The Hitachi 38mm and the HS4 Su carb have the same mounting flange size and we can supply two different length ram tubes 1 1/4" and 2 1/2" at $44.00 each inclding GST.
Sox for these are $42.90 inc GST per pair."

These guys cater mostly for British cars using SU's, but that is all the specialise in! I am going to give them a call later in the week and maybe go and make a purchase on the weekend.

Enjoy!

Also check Victoria British. They often put the velocity stacks for SUs on sale for about $12 each. Pretty cheap! They have several aircleaner choices iirc....
