Distributor

Can anyone tell me the installed height of the MOPAR Electronic Distributor on an LA engine from the block to the top of the plug wire towers on the cap? I have an MSD "ready-to-run" Pro-billet distributor but it's too tall and hits the 3 speed wiper motor. I'm running a 408 stroker in a 67 Barracuda FB with a Magnum Force K-member. Also, anyone know if a 2 speed wiper motor can be adapted to my application and if so, what part number(s)?
I'm not sure what this has to do with the original poster and his question about a distributor for a big block car but anyways I have the same setup with a stock K frame and it doesn't seem like there would be any problem putting the windshield wiper motor above it? It could be that aftermarket K frame sets the motor higher? But then it seems like the transmission would hit, something doesn't seem right. My 41 Studebaker has vacuum actuated windshield wipers? LOL
