Roger,
I too would hate to see a rare cross ram system destroyed. I also replied to 
Jim's inquiry note and suggested that he consider replacing the carburetors 
with a pair of Holley TPI injectors. This would preserve the cross rams (and 
the carburetors) and provide easier tunability. Parts for these old carbs 
are very scarce and worn components like throttle shafts or step-up piston 
bores are very difficult to service. If the carbs run as poorly as Jim 
indicated they probably need more repair than just a Zip-Kit.

I didnt get a reply from Jim but, like you, I hope he considers some other 
path. LGJ
