I was describing to a tech at MSD what our leading coil is and asking him if they made something that would take its place. He gave me this. Check it out and tell me what you think...

BTW apparently those posts are end caps and can be pulled off to expose a fitting like our coils use...

 

I have seen that set up on a car one time. but the owner got rid of it.. Could u ask the MSD tech. if that coil could be used with MSD 6A,6A-L, 7AL-2?

 

This is what I use on the leading plugs with a MSD 6A :
Acell GM DIS coil
and I mount it to the MSD Coil Interface Module (#8870)

I had heard of someone using the MSD motorcycle coil, but there was a problem with it - can't remember...I think it got too hot.

MSD also has a GM DIS style coil that I have seen in either Jegs or Summit Racing catalog. Neither website list the part, and the MSD site doesn't have it either.
