JA50N's 86 GMC: A rust wars story
I'm going to start a build thread since I got some pretty key components for my build yesterday, but first let's go back....
I picked this truck up in early May from a buddy on the Eastern Shore. https://live.staticflickr.com/65535/...9d9eedff_b.jpgUntitled by JASON MCKIMMEY, on Flickr https://live.staticflickr.com/65535/...b55e435f_b.jpgUntitled by JASON MCKIMMEY, on Flickr It's a 1986 GMC Sierra Classic 4x4 SB. It has a few rust issues as most do in this part of the mid-atlantic but I can deal with that. It also has had a 350 dropped in to replace the tire 305 which has less than 20K on it. Bonus. The day I brought it home: https://live.staticflickr.com/65535/...7ccdb413_b.jpgUntitled by JASON MCKIMMEY, on Flickr I started doing some stuff to the interior to make it more livable. https://live.staticflickr.com/65535/...c779b5b6_b.jpgUntitled by JASON MCKIMMEY, on Flickr https://live.staticflickr.com/65535/...2fd5efae_b.jpgUntitled by JASON MCKIMMEY, on Flickr https://live.staticflickr.com/65535/...6497cebd_b.jpgUntitled by JASON MCKIMMEY, on Flickr https://live.staticflickr.com/65535/...e0b4efc3_b.jpgUntitled by JASON MCKIMMEY, on Flickr LED dash lights https://live.staticflickr.com/65535/...d0738a8f_b.jpgUntitled by JASON MCKIMMEY, on Flickr https://live.staticflickr.com/65535/...bc481d95_b.jpgUntitled by JASON MCKIMMEY, on Flickr Now that the interior was livable and I could set my cell phone on the dash without losing it inside it, lol, I moved to piddling around with he exterior. https://live.staticflickr.com/65535/...772af909_b.jpgUntitled by JASON MCKIMMEY, on Flickr https://live.staticflickr.com/65535/...db264f2f_b.jpgUntitled by JASON MCKIMMEY, on Flickr https://live.staticflickr.com/65535/...4f1ec8cb_b.jpgUntitled by JASON MCKIMMEY, on Flickr https://live.staticflickr.com/65535/...cf4252e4_b.jpgUntitled by JASON MCKIMMEY, on Flickr I added some 2" bolt on wheel spacers to make this happen: https://live.staticflickr.com/65535/...3ffdf69d_b.jpgUntitled by JASON MCKIMMEY, on Flickr So after that, I just drove it around when I wanted to and didn't do much to it. I pondered where I wanted to go with it and finally after some lucrative OT at work this happened: https://live.staticflickr.com/65535/...3d7cb066_b.jpgUntitled by JASON MCKIMMEY, on Flickr 4.56 open diff 3/4 ton 14 bolt and dana 60 front to match. So now 35's are on the way and I am trying to decide on 3 or 4 inch lift to go with it. I don't want it to be super high. This thing will be used off road so it needs to not rub even when flexed and tires stuffed. So I think my path is clear now, lol. Stay tuned as I refurbish these axles, get my tires and wheels in, and pick out the lift. Any pointers for those that have been down this path is greatly appreciated! |

Nice truck and upgrades. You will need at least 4" of lift for 35's. I have a 4" with lt315\75r16 tires, which are around 34.5" , and while I have no rubbing issues, if it was flexing off road much, I'm sure there would be sheet metal carnage. The lower back corner of the front fender openings would be the first to go unless you do some fender trimming. You can see in the pic how much room there is. Wheel offset will also affect the clearance. Mine have no offset and I don't rub at all, but if you offset them out,you will probably rub.
Keep us posted. |
Re: JA50N's 86 GMC: A rust wars story
You have made good progress on it. Looks good.

Re: JA50N's 86 GMC: A rust wars story
My 81 k10 has a 4" lift with 35's and with my 8" wide wheels I can flex a decent amount before it rubs.

Re: JA50N's 86 GMC: A rust wars story
Well I plan on running a 8" wide wheel with a 4" back spacing and pushing the front axle forward 1" so hopefully that will allow clearance when stuffed of the 315/75 R16's. I will also be properly setting up the bump stops once the lift is on and I check clearances. If not, I'm not afraid of a sawz all. :devil: This truck isn't going to look nice ever. It's going to be purpose built and if a little bit of sheet metal gets in the way, that's not going to stop it. lol.

Re: JA50N's 86 GMC: A rust wars story
Update on the progress up to today. Have been painting the front axle and doing some research on where to get a Bilstein steering stabilizer. Seems like a pain int he butt to find. The compressed length of the leaky stock one is 14.75" and the extended length is 23.00" according to my rough measurements. Bilstein's website lists a model for a later model F-350 that is 14.96 compressed and 23.03" extended. I'm not sure it that will work and the bushings can take up that .25" difference. Offroad Designs has a Bilstein stabilizer listed on their website so I am going to give them a call tomorrow to see which one it is.
I also started disassembly of the 14 bolt. I got the Ubolts cut and off the axle and was able to disconnect the mangled hard lines. The axle is out of a 78 so I am assuming it has SAE fittings and since my truck is an '86 it should have metric correct? Any help here would be appreciated. I have my tires now but I think I am going to wait on the wheels for a bit. Any way, here's a few pics. As usual constructive feedback is welcome. https://live.staticflickr.com/65535/...8e317114_b.jpgUntitled by JASON MCKIMMEY, on Flickr Crappy leaking pinion seal is out and new one is in on the 60. https://live.staticflickr.com/65535/...f3e464a2_b.jpgUntitled by JASON MCKIMMEY, on Flickr https://live.staticflickr.com/65535/...4eaa47bd_b.jpgUntitled by JASON MCKIMMEY, on Flickr Brake calipers and pads should go on tomorrow as well as painting the short side axle tube and C-hub. Still waiting on the new diff cover to come in and once that is installed then I can paint the center chunk. |

Re: JA50N's 86 GMC: A rust wars story
So good news and bad news. Good news first. The front axle is ready to go under the truck.
https://live.staticflickr.com/65535/...b69635c4_b.jpgUntitled by JASON MCKIMMEY, on Flickr Bad news, got the hubs and drums off the 14 bolt and looks like the brakes are junk. All the parts aren't even there. https://live.staticflickr.com/65535/...5634e0f7_b.jpgUntitled by JASON MCKIMMEY, on Flickr Does anybody have a lead on a source for 1984+ backing plates for a 14 bolt that are the 11" brakes? I can't seem to find them anywhere. I can find the 13" brake backing plates but I'm not sure if I want to switch to those. |
Re: JA50N's 86 GMC: A rust wars story
Massive update. See pics below. the front should be going under the truck this weekend.
Decided to go disc on the 14 bolt. Here it is ready to weld shock tabs on and then go under the truck. https://live.staticflickr.com/65535/...684a34b4_b.jpgUntitled by JASON MCKIMMEY, on Flickr Wheels and tires mounted up. https://live.staticflickr.com/65535/...5185844f_b.jpgUntitled by JASON MCKIMMEY, on Flickr Custom made Alcon front springs with the pin moved 1" forward. https://live.staticflickr.com/65535/...f31500fa_b.jpgUntitled by JASON MCKIMMEY, on Flickr Other suspension goodies, new shackles front and rear, all new mounting hard ware, etc. https://live.staticflickr.com/65535/...f03676c3_b.jpgUntitled by JASON MCKIMMEY, on Flickr Shocks are on the way and hopefully will have them by the weekend. Stay tuned for more. |

Re: JA50N's 86 GMC: A rust wars story
Sweet truck! I love your build. Be careful with those harbor freight jack stands. There Is a recent recall on some of them for failing!
