I think it is a '36 and not sure when it was run last. It would need some work to get it there.

COS399 · 01-26-2015, 10:19 PM

Here is a cool ad photo from back in the day.

**Dieselwrencher** · 01-27-2015, 08:04 PM

It would be really cool to slam that body on a newer school bus or FL70 chassis.

84chevyguyid · 01-27-2015, 09:06 PM

Hey that tractor trailer combo would be cool to haul the wheelers in, get that put together and bring it this summer to the dunes!!

Yeah, I will get right on that.

Yep, that could be an option. I need to drag it home one of these days and measure it up in case I go in that direction. It has a wooden floorboard and a two speed rear axle.

Got a new wheeler to load in it...

When my kid was that age you couldn't get him off his 3 wheeler toy. We had a dirt pile in the back yard and he would push that thing to the top of the hill and then ride it down. I got my kid his first ATV at the age of 2 1/2 years old and he raced it at 4 yoa.

Time flys by.

Until you see the price for insurance that allows it to haul a trailer. I have a Mack that looks a lot like that old international.

**Dieselwrencher** · 01-29-2015, 01:46 AM

Even his own big ol antenna!

Nice!

**Dieselwrencher** · 03-02-2015, 08:57 PM

That looks like it was a pretty cool trip!

COS399 · 03-19-2015, 11:05 PM

Mike- that looked like it was fun. We are getting closer to giving you dates for our St. Anthony's dune trip. I have to work around football and basketball camps that my kid wants to go to. I will PM you with the dates as soon as we can firm them up.

COS399 · 04-27-2015, 07:37 PM

No progress to report on this project. I did however buy '06 GMC with a Duramax/Allison combo and I have to tell you that I am impressed with it. Time will tell but one day I may be doing a Dmax/Allison swap into something.???

MTCK · 04-27-2015, 09:09 PM

Cool. Any D-max pics?

COS399 · 04-27-2015, 11:06 PM

Here are a few pics.

COS399 · 04-27-2015, 11:14 PM

I will get you a few more tomorrow that don't require a magnifying glass or cheaters.

**Dieselwrencher** · 04-28-2015, 12:24 AM

Very nice new ride!

COS399 · 04-28-2015, 07:19 PM

Thanks Ryan.

Here are some better pictures. It is a SLT model with all the bells and whistles and runs like it has been modified a little.

carboncrew · 04-28-2015, 07:49 PM

Looks like you need to clear some space in the garage. I'll be up this June to take the red one of your hands...just trying to help ya out!

Thanks, but I think my kid might fight you over that one.

Bring that nice black one up here so my kid and I can check it out. Oh, and you have to trailer it or drive it back home in reverse.

I might have to see if your dad will let me put a few on his lot to sell.

**Dieselwrencher** · 04-28-2015, 09:47 PM

Did you lose forward gears in the red truck?

No, just temporarily sidetracked. I found the International, had to change the motor in my '96 PSD, filmed all the HS and JH basketball games (my boy's team was undefeated and won District Tournament

), towed my Fifth wheel toy hauler down to Tucson and traded it for a travel trailer toy hauler and got to do some riding at Coral Pink Sand Dunes on the way home. I will get back on it as soon as I can get rid of my PSD.

Hankster · 04-30-2015, 05:57 PM

sounds like you have had a good time none the less thats all that matters!

Yes, we had a good time and I wouldn't trade any of it. I met up with 84Chevyguyid in Idaho Falls and he bought my family and I brunch on the way to Tucson (Thanks again Mike).

I jumped over to your build thread and your project is coming along nice. Other than my wife's Yukon XL I am die hard diesel guy. Before that however I was a BBC person. I have owned my share of these squares. but only one of them was a 1/2 ton all others were 3/4 and 1 tons. Keep up the good work on yours and good luck with that annoying vibration.

Thank you sir! We are pretty sure the trans is/was the torque converter.

656mx · 06-26-2015, 10:32 AM

Awsome build tread! I've read the whole thing like 4 times. Did you ever figure out if it is too high for your fifth wheel? Doing a 24 valve 47re swap in my 91 crew and need to order the lift. It will need to tow a toy hauler in the future and I can't decide between 4 or 6in lift.
