MSD distributor guru

Yes, David Ray a member here. I'll be calling him shortly to discuss the issue of reworking the distributor.
I'm trying to use what I have & get down to one manufacturer as far as ignition goes. Right now I have an MSD 7AL2 & a Mopar HEI distributor that isn't compatible with the MSD crank trigger on the car. MSD is no help as far as making all of the parts play well together. I think between David & myself that we can get all of the parts working together.
I have a good friend in CA who can help u out * if u need his contact info let me know , he has built me several non vacumm oem recurved race units .
