HEI style distributor cap

you might mean Davis Unified Ignition (D.U.I.) at

I bought one to put on my 318 thats not in the car yet. Took the distributor out of the 273 the other night to see if it would fit and i am very nervous about it, it is BIG. I know that i will have to a bolt that the wiper motor mounts onto, hopefully nothing else will be in the way...

Anybody else have one of these?

I don't have one, but D.U.I. sells a distributor with an externally mounted GM module that they recommend for Darts,Demons, Dusters, and pre 1970 Barracudas that cannot use the D.U.I. (HEI type distributor). I assume they're implying that the HEI type won't fit an A body..........at least that's what I conclude.
