is 94 the year the body style changed? if so the kit wouldn't be perfect because it is designed for a different body style. they should definitely be able to get you one. i'm sure we have a vendor here that has them. Have you checked out the vendors here? posting in the request a quote section usually gets a quick response and the best prices. Any vendors that can provide you the kit you need can message you a price. It's a great feature here

yes if they give you a turbo back system for a 94 and up truck the down pipe wont work and if your truck is 4x4 then the transfer case will be in the way oh the tubing that works with a 94 and up truck. ask for just the stack kit and if it comes with the 90* elbow for below get that too. i take it your upgrading to the 4" exhaust for the turbo down so get the right 4" down pipe for your 1st gen. then just go to ur local napa or something and get a strip of 4" exhaust flex tubing the length that you need to connect your down pipe and to the stack kit and two exhaust band clamps. that way you can get up and around the t-case much easier with the flex tubing. oh and depending how far the down pipe may reach underneath you may need to take a few inches off of it to have enough room to get the flex pipe to go on. hope this helps

Careful with how much flex pipe you use if your state has inspections. In Pa we can't use over a certain length of flex pipe.

I'm running a 2nd gen exhaust and the downpipe is the only piece that fit good. The only thing you need to make it work is the cast elbow off a p-pump 12 valve. I posted a picture in this thread about halfway down the first page.https://www.dieselbombers.com/5-9l-r...h-exhaust.html
