Question about headers
My '78 C15 is bone stock with a 350. I'd like to get some headers for it, but I've never put headers on before. Is there a brand that is budget friendly that anyone would recommend? I don't want chrome headers. Would a used set be ok to use? On a half ton truck, is the starter something that I...- ulm4lyf

Question about exhaust.
I have a '78 GMC C15 with a bone stock 350 and original factory exhaust. I would like to replace the exhaust with dual pipes and for it it to have a more agressive (but not overly so) sound. I don't want to run straight pipes. About how much $$$ am I looking at for a muffler shop to do this? I...- ulm4lyf

Please help a non-electrician
Blower motor fuse keeps blowing. It's a 20 amp fuse. If I put in a 30 amp fuse, the blower motor works until I put it on 'high' then it blows the 30 amp fuse. It has a new blower motor, new switch, new relay, and new resistor. I'm not seeing any obvious loose ground wires anywhere. I've looked... -
Door Pins
My driver side door is sagging pretty bad, so I've gone ahead and ordered some replacement door pins. The videos that I've seen appear to be pretty straight forward, but have any of y'all replaced them yourselves? How big of a pain was it?- ulm4lyf

Window regulator part
I am going to replace the window regulators on both doors. I have ordered all of the parts from the picture from LMC except for #5 - "roller and rivet" because it is out of stock with no backorders. Is this something that will come with the new regulators , will I have to find them somewhere... -
All new weather stripping and door rubber but leak quite a bit when I run a water hose over them.
It's like there isn't even any weather stripping or door/window rubber even there. What did I do wrong? I am scared to drive it in the rain.- ulm4lyf

Don't really know where to put this, but have any of y'all ever had to get a bonded title, and how big of a pain is it?
I may have to get one because of reasons. -
Not completely new here, but I had a question and didn't really know where to put it. Did any of you attend WyoTech?
I did in 1994 at the original location in Laramie, WY. At the time, it was called Wyoming Technical Institute. I don't even know if it is open anymore. Regardless, I only did mechanic work for a few years, ended up going to a regular university, and now teach science to 10-11 year olds that say...- ulm4lyf

More wiring fun...this time with a video.
I have found some loose wires on my 1978 C15, and don't have a clue where they may have gone in the past. This is in addition to the bad ground that I have somewhere. I know how to wire things up to make them work, but I'm at a complete loss when figuring out why something electrical isn't...- ulm4lyf

Head scratcher for you
My turn signal works fine until I turn on my head lights. When I turn them on, weird things happen. The left turn signal no longer blinks, and in addition to that stepping on the brake pedal not only activates the brake lights, but also activates the front side marker and turn signal lights. I...- ulm4lyf

Weird reverse issue
TH350 When the trans is cold, like sitting for several days, when I put it into reverse it doesn't always immediately go into gear. This almost never happens when the truck has been running for a while. Am I looking at a complete overhaul? Truck has very low miles ~57,000.- ulm4lyf

Any tips about a rear wiring harness replacement that I should know about?
Right brake light isn't working, so I change the bulb. No luck. Yesterday, I crawl underneath to see what horrors await. The previous owner (I bought my truck in July) apparently hired Wolverine to splice in a trailer harness...a couple of decades ago. There were exactly zero connectors used...- ulm4lyf

Wheel question about a 1978 Sierra Grande
I have a 1978 Sierra Grande 15 that I just bought. It has some ugly stel wheels with hubcaps that i don't like, but I don't know what size wheels and tires that I could buy that would fit. I am looking for stock size/fitment. The door sticker denoting size is missing.- ulm4lyf
