Where can I send a Bridge to be Modified to 3" intake?tempImageczA2OA.jpg

I know WCFab offers a Billet one, but the installation requires cutting the hard fuel line & installation of rubber line. I'm no interest in altering it.
I've been looking around but cannot seem to locate any of the older 3" Modified ones.

i tell people, if they want to do that, they are better off doing the LBZ clam shells and y-bridge, then mod that y-bridge.

at the end of the day, the heads are the restriction though.

I had thought about doing that, but a lot of exchanged hardware to only come up against the head restrictions.
Only reason I'm Drinking the Cool-Aid was to make a smooth transition from the cold side 3" Intercooler pipe to the Bridge & eliminate the Heater Delete Plug.

a cummins drain plug fits nicely in the heater hole. threads right in. I think its either the 12v cummins or the 3rd gen. little google fu will tell ya. thats what i ran for many many years.

IIRC the 02-04 y-brige is all the same. its the 01 that is different as it doesnt have the 45* turn where the intercooler pipe connects.

On my 04 I punched out the heating element and tapped it and ran my boost gauge from there.

tempImageDvLbUO.jpgtempImageS8Bv6u.jpgDoes anyone offer a Modified Y-Bridge? I have The Federal Bridge to work with.
I may make my own Jig & Fab one if need be, Just need the time to do one.

Any suggestions?
I'm thinking of building a Jig to hold the lower Bridge & the placement of the 3' Intake Side. I'll have to compensate for my 3" HSP Intake horn.
Anybody know of someone to take care of this for me, as I don't really have the TIME?
