Sean it sure looks to be close. I can't see Any differences in the two in photos. However being a different part number they may have some difference such as actual mounting hole dimensions or something. I only have an old -30 45" coil to compare and they are quite different. Erik K

I have both of these coils and the only difference I see is that the top mounting hole and bottom slot are 5/16" on the big twin vs. 3/8" on the K, early Sportster. The mount bracket on the latter is about 1/8" longer but the hole/slot match.

Great info thank you. Also I think the K used the small 5/16" studs until 54 so that is good to know.
