So, I purchased an 100amp Delco alternator from 74M35A2 almost two years ago and only got it put on about a year ago. Of course it has to be idled at 1200rpm to produce what it should at 750rpm and I havent used the truck hardly at all this year and now is the time to confront this issue before...

I finally got a chance to take some videos with my new phone that have good audio so I posted them on Youtube. The truck has been making this clanking grinding noise that does not really start until after driving the truck around for a good 10 minutes which tells me it probably has to do with...

Just wondering if anyone here on the forum has removed the silencer ring or did some sort of modification to where there turbo sounds like this Cummins 5.9 in the video below....and is the stock air intake on these trucks large enough to just simply modify the turbo greatly improve turbo sound...

Ok, so I have not drove the truck much in the past 6 months and actually installed a new air dryer after the old one froze up last March driving it back from auction. Installed new air dryer and was puzzled because it would not sneeze after first starting the truck and it building to 120 PSI...

So, unfortunately I need a torque converter for my transmission now. Cant find any on the auction sites either. Can anyone direct me to a place or someone that has these at a reasonable price?

So, I have had this ongoing issue with my M923A2 ever since I bought it back in Feb. The problem is that there has always been a metal clanging sound that comes from directly underneath the cab where the Transmission is and it comes and goes when I take the truck out every week. Some weeks it...

So, can you even buy a 24V amp for a stereo in these trucks??..as I was about to pull the trigger and buy a 24V head unit for 4 speakers and a Sub that requires an Amp...then my buddy is like...you may not be able to get a 24V amp.

So, I have tried to find an auxiliary switch panel like is in Ford Superduty trucks that I can mount under the dash of my truck to service some ancillary LED lights I will be installing. Also, I plan to install a stereo in the coming weeks and will be mounting a head unit as well. Everything I...

Ok, So I probably put about a 100 miles on my truck since yesterday and finally my luck ran out and I encountered another issue. Luckily I was close to a good place to park the truck not far from home. Truck was building air fine for about an hour driving around today and all of a sudden my low...

I've got a couple pieces of the foam insulation that are starting to come apart inside of the Frankencab. I have only seen this type of foam padding in the Frankencabs and wondering if anyone knows where you can this exact kind foam insulation? I'm one of those guys that it drives me nuts to...

This was an ongoing process for weeks, but it is finally all done after today. It only took 6 1/2 inch pilot tip and Cobalt tip drill bits plus a reamer bit to make all of the holes. The top lid of these Frankencabs is made of tempered steel and was a big pain to drill though....now I know why...

So I installed LED Park and Tail lights from Riverside MFG a few days ago and they work correct in all modes except the Park light mode. When in that mode if I turn the signal left or right...it just lights up which ever side you turn the signal to up full brightness and that side stays that...

So, I had to bypass the lines when my air dryer valve got stuck open back FEB in 15 degree weather driving it back home from GA. The low pressure indicator light would always flash and the buzzer would buzz and then once you bypass it it stops working...which I think is normal(although I could...

Ok, So I had the truck out for a couple hours this evening between 6-8 after it sitting for 3 weeks and it ran just fine. Engine temp stayed between 170-180 driving around and stopping at red lights for 2-3 mins at a time sometimes. It seemed to take forever to warm up during the late Winter...

I am wanting to change my stock incandescent bulbs in my marker lights on my M923A2 over to all LED bulbs without having to buy a whole new light LED housing...as I have read I can do. Can someone please refer me to which LED bulbs I can use to replace the stock incandescent bulbs with?

Ok, obviously there is space to mount two good sized horns under the hood of an M923....so can anyone recommend a good set of horns that has a much deeper tonal sound exactly like what's in the videos below...and would mount easily in the existing space...or would it require modification of some...

Ok, so I am having a hard time finding the LED cab lights that are on the newer LMTV trucks from Oshkosh as I have looked on Grote's site who supposedly makes them and still can't find them. I have also seen a light bar setup for the Amber cab lights as well like in the second pic below...

Ok so, I picked up my truck earlier this week and the driver side seat would not stay up when you inflated it and I ended taking to a truck stop and they said it was the valve under the seat that was bad and letting the air leak out. You could hear it hissing out slowly when you would inflate...

I am going to pick up my first MV next week which is a Frankencab 5 ton and one of the pieces of Rubber door stripping has come loose as shown in the picture below. What are some suggestions for the best thing to adhere it back in place with? I want to do it as soon as I get the truck before I...

The truck I have been looking for is in Atlanta and I live about 500 miles away. Can anyone do an inspection on this truck as it does not have batteries and says not running, but looks brand new and had a recent rebuild... so otherwise I would not be hesitant to bid. I just don't know what to...
