I am looking for the correct part # for the cable clamp that secures the spark advance cable to the bottom cylinder bolt that holds the cable housing from moving . I am sure many different clamps will work . from looking at many pictures i think the clamp has a separate bolt and nut to tighten down on the cable without loosening the cylinder base nut . Thanks if you can help

The '38 up clamp is two piece with a screw and nut to close the clamp around the cable. It is also built with a slight twist in it to line up the cable, repops may not line up without a slight tweak. No clamp appears in either the '37 or '38 parts catalogs for the '37 U series, the clamp is new for '38.Robbie Knight Amca #2736 -
The spark cable you are looking for is a 3392-37A Timer Control Coil Bracket , Lower, with a 3371-36A Bracket Clamp held together by an 042 Fillister head screw 12-24 by 1/2 and an 0255 lockwasher.
There is also an upper bracket under a head bolt on the front head. This is a 3392-37 Timer Control Coil Bracket, Upper. This number is for the complete assembly They are listed in the parts books for 1937, 1939, 1940 and 1936-48 Big twin. These brackets are shown in Bruce Palmer's books; second edition: pages 127, 304 and the third edition: pages 131, 348.
Neither is made by Colony but I was able to use 3371-36 Throttle Cable Bracket for 1936-1948 O.H.V., Colony number 9005-4 with a little tweaking on my 1937 UL. Hope this helps.

Dave, the spark bracket and throttle bracket are pretty close in construction. That's what I've advised my customers to do.Originally posted by ammorest View PostComment
