Does your base plate happen to have a port on the back of it? If so you could put the hose into it, if not then drill and tap you spacer is a good idea over the intake IMO. I use to run the ball valve set up but switched to a push pull valve for a cleaner set up. Contender Performance sells them. I will try and get you a picture tomorrow
Is this the setup you were talking about? Looks like they sell 2 versions with the only difference being one comes with a bracket. I would like to see those pictures if you still wouldn’t mind. Especially how you have it set up inside the car.
Was the ball valve set up working good? I get that the shifnoid system would probably look slicker. I also like that it’s a one stop purchase rather than tracking down fittings and hose and a valve. Just trying to justify the extra expense. Thanks!
