Here is the link to one of my previous posts. This is a great forum, it has helped me so much with my build to date.

Also why would my gauge cluster lights not work but head lights work fine and turn signal indicators work fine as well? What can I check?

I simply bought the Dual headlights LMC upgrade for new generation halogen headlights for $28.00 it comes with relays and everything pre-wired, made plug and play to use old school headlight plug ins to the Old OEM truck harness. I installed the new headlights that use halogen bulbs in fixture housings. I cut all the old plug ends off and hard wired everything into a whole truck harness I found on Ebay for $170.00 bucks. End result completely rewired old truck. Also your original motor was a 307 V8. I've included some pictures of how to lower the rear with leaf springs on the cheap. We pulled 3 leafs out, bought new plates and u-bolts to clear frame and built new shackles and relocated shock mounts.

Here's a diagram

Thanks for the diagram but it doesn't really help me with my gauge lights issue. I can't really see what's going on here. Also is there a diagram for GMC "4eyes" up front?

asesapie · 08-30-2015, 01:11 AM

Anyone on gauge lights and the center two head lights?

70blackfish · 08-30-2015, 12:49 PM

fuse? or headlight switch, pull the cluster and check the plug, and the bulbs.
use a test light?

Well I am likely going to use performance online.com's 4" drop leaf springs for the rear and there disk drop kit for the front.

Anyone ever used these? I think it should make a nice stance and look for the truck. I'm also planning on upgrading the motor as well from the stocker it is.
Just looking for around 300HP, nothing crazy just something with some nice get up and go.

i used POL drop springs and i like em

asesapie · 09-12-2015, 08:57 AM

Cool, what amount did you drop the rear? I was thinking about the 4" drop springs in the rear. Don't know if I'll need to notch he frame or not though.

Also I need to change the gasket on my oil pan. Anyway to do so without pulling the motor as I don't have a hoist?

My dash lights didn't work when I bought my truck. I removed all old bulbs and put in LED's.
Gauge bulbs can be reached from under the dash. You don't have to remove the cluster. A few of them were kind of a beaotch

They simply twist on and off.

Well had to replace the head gaskets on the truck. The inside of the cylinder sleeves look great, no ridge. There was one lifter however that had some putting in the center. The cam lobe looked okay from what I could see but would assume it's in poor shape as well.

I'm thinking it might be worth it to replace the cam but will it need new bearings or can you just take old out and replace with new? I'm still very new to be whole V8 thing.
