Hello!! I am retrofitting a thunderbolt IV ignition into my 81Mercruiser 228. I have found pictures online where the module is mounted on manifolds where the riser was in the center. . The riser on my manifold is at the end. Anyone have any pictures or ideas of where to mount the module? I'm guessing I'll just have to make a custom bracket.. Thanks

I Mounted one to the transom on a 1984 Bayliner with a Volvo setup. Ran sooooo much better!
