Hey all- Its only been just over 2 years since I started my 1989 GMC conversion and its been a long long road and its finally starting to look like its comming together :--)
:--)
Anyway, here is a detailed list of what all was done to the truck if you are not aware of my project. It started out as a 1989 Reg-cab long box 2wd dually. I started the project in the hopes to just have the Cummins under the hood and it grew fast from there! Most of you will notice that its no longer a reg-cab but now a crew-cab. I picked up the cab which had the fire wall pushed in slightly and were unable to pull it. After talking to a few body shops it was decided to cut the firewall/half the A-Pillar off and graft my existing 1989 firewall onto it. There for the truck is a 1989 crew-cab CK truck (never made by the factory).
Anyway, here is the list of things that were done.
-Cummins Conversion - 1996 5. 9 Cummins (rebuild by Hasiley Machine)
-4x4 conversion - used a 1989 Dodge Dana 60 (ARB locker)
- coil spring setup
- 2005 Ford Trailing arms
-2004 NV5600 6-speed Transmission (Haisley Comp Puller Dual disk Clutch)
-1997 NP241 HD (custom built with GMC speedo)
-2004 GMC AAM 11. 5 Rear Dually Axle
I will continue to update you all on my progress and keep adding pictures as they come and feel free to ask questions or post a response... positive or negative.
Thanks... RyanB
