I'm not able to find a correct replacement vacuum advance for 57 y-block 292 engine. It needs to have a straight linkage as shown in first picture below. All I'm able to procure is offset linkage as shown in second picture below. No suppliers show good pictures. Distributor is marked with "FoMoCo FEU-12127-A " as well as "FEK12131-B ". First picture below shows the damaged existing advance. I expect prior owner tried to rotate distributor with length of pipe over the vacuum fitting and bent it. I've ordered replacement twice and gotten offset linkages. First supplier was Amazon. Second supplier was Dennis Carpenter B9AF-12370-A (shown in second picture). It looks like LMC 47-1414 might be offset link as well, but it's hard to tell. Does anybody know where I might find one? I haven't seen anything from ebay either.
