I did give it to them and I saw the same thing in their catalog. I have a backup 9-1381A for my 318 Barracuda, but it won't fit the Prestolite. They do list IBS Series units under the 1959-1971 Big Blocks (383-440), and for the Studebaker (1584) the one they recommend. Seems like the one for the 340 unit with dual points would be a likely option. But...
