Default Old school Class 8 Prerunner.

Guys I have have had a rough last couple of months. Had my car repoed , had to quit my new job, and been generaly depresed. The good news is I got my expenses down to $500 a month, my wife receives $600 a month, so we are ok just not great.


End of *** story, I joined a build off on another site and have until July 4th to finish. I had to change my plans(can't afford new parts). Was going to build a Hpi Mtdt body. Now I am going for my 79 F150 J concepts body. Using donor parts off an old Rc10gt, front arms, spindles, 2.2buggy rims. The trans is out of an old Traxxas boat, rear axle Wk,with an Ax10 pinion,Mip driveshaft, 2.2 Proline Flatirons.

On to the pics...
The Trans.

Wheelbase mockup.

Rear axle, front end.

New chassis, too short, too narrow. Narrowed the front 1/2".

Added braceing and trans mounted.

This chassis is only for mock up and being used as a pattern.

So the wife only gave me an hour tonight to work on the truck. I made two lower link mounts, set the wheel base and played with the ride height.

It is looking good. I am wanting to see how that motor and gearbox works out.

Thanks walter, I to am looking foward to seeing how it works. It is a 2to1 reduction box with what looks like 32 pitch gears, and I think a 20t 550 motor.

I like how this is turning out so far, but you'll probably wind up needing a bearing to support the driveshaft at the end of the chassis pan. Maybe you can use a rear knuckle off a stampede or something and bolt it to the chassis with spacers.

Thanks Crazy Drew the drive shaft is in an aluminum tube supported by a bushing. I never thought about the forcesof moving that driveshaft and will be getting a support at the end.

Cool, I just see bending loads becoming a problem on the driveshaft. I really like the idea of a boat gearbox and driveshaft but was concerned about it bending. I know you're on a budget with this build and it would suck to see you have to buy another gearbox for something that can be prevented with $10 in parts.

A friend of mine gave me a nice big chunk of 1/8" aluminum.

I drew out the chassis and drilled holes in the corners than started cutting.

I folded the back up for the trans support, and drilled the holes for the front end.

Next I put the front suspension on and put the rear link holders on.

Here is how she sits now.

being in a tight budget situation always sucks, but sometimes the coolest builds are the ones cobbled together from leftovers. looking forward to seeing this move.
