I searched for about 3 years to find the 1991 I wanted, specifically for the 4L80e and the round pattern NP205!

I've contemplated going 36" or 37" tires.  I have full articulation and zero rub issues and I did not want to cut any body work.  Plus...no step bars!  It keeps the shorties out, and I have to help my wife up in it by grabbing her a&$! Lol

thats funny gives you good reason to grab it. as they get older they dont like that, but you have a reason lol. i did get a used 35 and 37 mounted on the wheels im using to see the difference so i know for sure. but pics on your build helped alot.

One thing half to figure didn't even think about is 4l80e is longer than turbo 400. So my shifter for the np205 won't go back in hole in floor. And I don't want to move seats back. I saw some people heating it up and bending it but think on mine will half to be longer also. Don't think just bending it will be enough.

It may not go in the same hole but the 4l80/205 did come stock in 91.

It's a good thing I have long legs cause I moved my 4l80 back 3" and the 205 shifter doesn't interfere with the seat if it all the way back

I wonder if the shifter on the 1991 crew cab is a little different. Not that I could find one lol. Be real hard to find.

Don't think I took any pictures but from memory they're the same size and all

ehjorthen yea thats nice truck. glad you choose ls swap lol. i started out going to do cummins swap but thought in long run be happier with ls swap. since this is going to be my daily driver. glad i saw you build gives me good pics of your truck with 35 inch tires. you have 8 inch lift. doesnt look bad with 35 inch tires. i wan to run 35's for main reason its a daily driver. but just dont want the huge gap between top of tire and bottom of wheel well. looks like 35's will work for me and too i have a 4 inch suspension and 1 inch body lift. i dont like body lifts. so i did the 1 inch body lift just for extra clearance for exhaust and the high angle transfer case ebrake.
We have a 4" spring and hockey pucks on the body mounts
(No need to pay $$ for a body lift when hockey pucks are free )

And 35s and they fit fine
A little fender trimming and you could use a 2" suspension lift with 35s

Exhaust is getting put on this week. I went with Gibson mufflers. Didn't want it to loud. Mufflers will be just passed cab and dumped before rear axle. So it doesn't show out back.

Truck has power now. Headlights, horn, tail lights all working. Rearview mirror with temperature and compass are working. Showing 100 degrees and that's about right.

4wd shifter was modified to go back in hole added to it from underneath so doesn't show in cab.

Exhaust about done. Mufflers are just pass cab and dumped at rear axle.
