Gee, Bill- you keep trying for those SU's...Looking for a pair? I actually
know of a junkyard local to me with several in the trunk of a Spitfire. I
understand the SU's will fit my head as is, so the ones I have are staying
with me, thanks :)...But I'd be glad to pick up a set from the yard if you
like- just have to get a price for you. (I do have a spare SU manifold,
tho...but it has the ventilation tube on the side. But my 4-2-1 exhaust is
likewise being retained... I may have access to another- haven't had the
hood of that car open yet- they have it pushed against a truck, and it is
hard to move.)
Scott
64 Herald 1200 Convertible, soon to have dual shiny SU's...
