Just retired and am working on a 1949 Chevy pickup. A 3600 3/4 ton with a newer 1958-62 chevy 235 engine that I am installing with original 4 speed SM420. Not what I thought I would be doing at 61 years old. Needing pictures of dual carb set-up linkage. I have a thickstun intake and 2 rochesters. I can't figure out linkage its binding. Will I also need to shorten the linkage from footfeat?
