HEI All in one

hows that fit in an early A. Old distributor barely clears as is. I have a HEI (actually bosch module) all in one and have been looking for a year for just a stupid cap clip. Everyone sells the distributor, no one knows who makes it or where to get parts.

This guy uses one in his thread about the swap. Looks like a tight fit but it does fit. That's what got me looking at these in the first place. Though, I admit, the idea of putting one together from stock parts is looking better to me.
