1972 K-10 build questions

[azsmokey]

Well, we finally got our donor truck, a 2003 Silverado SS with under 20k. Our plans include transplanting the 6.0L, 4L80E, interior parts and other miscellaneous items.

A few questions:

1. We have entertained the option of using an electronic shift transfer case. What options are out there, that have some level of reliability. I have found the NP243. Are there others that will work in this application?

2. The doors on this truck have the wing/vent windows. Can I remove the vent section and replace the door glass with a solid piece or do I have to replace the entire door?

3. To keep costs down, we have opted to keep the 12 bolt rear and Dana 44 front. Is there anyone that makes a front and rear disc brake kit? I have only found a front brake kit for that truck as it is a 4x4. There are a number of brake kits for the 2wd trucks...

4. Are there companies that make a winch bumper for 72? I am not able to find one. There are ample models for 80+ Chevy trucks. How different are the front frame dimensions on the later model Chevy trucks than the 72? Are they at all compatible or close enough that they could be modified to fit? I would like to research both types of winch bumpers, both external mount and hidden winch mount. I dont know which would look best on the truck yet.

5. I see a lot of trucks that have had the drip rail removed. I really like the clean lines of the truck when it is removed. How difficult is it to remove the rail? What is entailed in its removal?

6. I would like to use as much of the 2003 parts as possible. Can I adapt the factory gauge cluster? The HVAC controls? Stereo head unit? Steering column with steering wheel? (Airbag removed of course..) I would like a tilt steering column in the build up. Has anyone tried to use a late model column in this type of truck. Are they compatible? Would I have to use the steering rack etc... from the 03?

7. I would like to use a 4-6 inch lift for this build and use 33-35 inch tires on 18 inch wheels. This truck's ride was nothing short of rough in OEM form. This is to be expected from a truck with solid axles and leaf spring suspension. Is there a setup that can be used on 4x4 trucks with a lift that will ease the ride? I have seen 4 link systems and trailing arm setup's, as well as coil-over's, however these have only been listed for 2wd trucks. What are some options for suspension upgrades to this vehicle with a lift?

I think that is enough questions for now. I appreciate any information and advice that can be given. Thanks!
