Well, I was thinking about a setup like MArk has on his then using a regular coupler like the 1st pic and then using a razor knife to cut a lip in in it so it seats. Or using something like the second pic on the bottom if I can find the right piece.
I am using my old intake and trying to make one for my neighbor who cannot use his hands very well (stroke). He does not want to cut or hurt his truck so I am using mine to make it and try and find a way so I dont alter his truck other than the intake from mine. You guys have given me a ton of ideas.
