Actually looking at it i feel the hitch is stronger than the truck frame so have been a little concerned.

So by adding the brackets your making do you feel that it is stronger than using a drop hitch? lets assume i needed a 4" drop and the brackets accomplish this drop.

Hate to say it but i don't understand your formula

I was just typing quick on my smartphone, sorry about the rough formulas. I'll try to type up a quick document that outlines it.

You would be better off with a set of brackets like I've got since they bolt to a longer section of frame. The load on the frame is directly proportional to distance between the front and rear set of bolts.

Thanks, I am having fun and not sweating scratches with this truck!

Vintage Windmills · 03-17-2014, 12:39 AM

Belts and seat in. I like the belts but the hardware kit didn't have the coarse thread 1/2-13 bolts. also I should post pics of the driver side retractor position for some opinions. the tank forces it out and not in the best spot. I may just drill and mount it to match passenger side angle.

No need to update the formulas for me, i did way too many of them during my machinist apprenticeship back in the 90's

I get what your saying tho, the breaking forces on a drop hitch would transfer to the hitch and frame so a longer hitch flange would help distribute the force along the frame. with my rear fuel cell i was having doubts about drilling thru and sandwiching the tank flange with the rear bolt of my old hitch, still thinking about possibly adding some kind of bracing to the new one.

Maybe after I'm finished struggling with my rear quarter damage I'll spend a little time rethinking the issue.

Yep, the rear tanks are nice but complicate things. I'd like to go to a rear tank at some point, need to read up on what you and others used.

Vintage Windmills · 03-26-2014, 08:00 PM

Swapped the rebuilt carb on the truck and took it for a spin. Got insurance on it now too! Nice to have a seat in it

Pulls to the right still, need to work on front brakes and tune the engine, she stumbles a bit on accel but then pulls pretty good so should just be a matter of tuning.

Vintage Windmills · 03-26-2014, 08:06 PM

Picked this diesel truck up on Saturday, Not sure what truck the parts will be used in. Its got a gearvendors setup, overdrive (getrag 5spd), dana 60 front and 3.55 gears.. so you can idle at a cool 50mph! Shes rusty and the Dana 70 rear is junk.

I think for now I'll swap in a Dana 60 3.55 rear I have to see how good the driveline is and how I like the gearvendors.

glimmertwin01 · 03-26-2014, 08:22 PM

Crusty Old Dodge... but it might make a good winter rat... u have all summer to seal it up, then beat it like the rented mule it is...

**Dieselwrencher** · 03-26-2014, 10:53 PM

Nice score on the 1st gen Dodge. Is the GV before the Tcase or after on that truck?

Maybe, shes so rusty though, chips fall off when you slam the doors. One of the rear shackles Is almost rusted through too. Its crazy how these trucks rust. Its also crazy how cramped the cab is. Even my 88 chevy was so much better designed in the cab especially. I know, preaching to the choir here, this is a chevy site!

Thanks Ryan. I'm still looking for the parts for the other cummins at some point. This one has the overdrive after the np205, per Gearvendors install instructions. Does this np205 have the same output shaft as the one in my ochre truck? Trying to figure out how easy it would be to swap in the K20. Still surprised this truck had one with the 3.55 gears.

ryanroo · 03-27-2014, 07:16 AM

the 205 in the dodge is a 29 spline. it is specific to dodge manuals of that vintage. not a bad piece to have laying around. you can use it with any dodge manual(that i know of, the newest stuff i dont know the specs on) that came behind a diesel. so if you want to swap a cummins into an old chevy and use a 205 that is the case to have.

Jud, I don't believe the dodge 205 has the same output as the chevy. If I remember correctly, the dodge ones are larger in diameter. I could be wrong though. I've never tried to put a dodge yoke on a chevy 205. I could be wrong and they could be the same. That woiuld be nice. The dodges use a 1410 u-joint any way so I'd use it over the stocker GM one anyway.

ryanroo · 03-27-2014, 09:20 PM

wow, i totally missread that... haha

the rear output on the dodge and gm are the same... i think. i do think the dodge diesel varient had a different PN, but it was dimensionally the same as any gm fixed rear 205 with a plastic gear. the difference was in the machining process to make it a bit beefier. there is a difference in the rear outputs with metal speedo gear, but i dont know how it would affect the GV.

the front output will be a bigger version. the dodge was 32 spl where gm was 30 spl.

Vintage Windmills · 03-27-2014, 09:59 PM

Thanks guys, I could have been more clear. I am thinking on just removing the gearvendors by itself and mounting in my ochre truck if it will bolt right up. Then drive the dodge w/o a gearvendors for a year or so until I'm ready to transplant the cummins, trans, and dodge tcase.

Vintage Windmills · 04-09-2014, 08:24 PM

Time for an update, scrubbed the hood and it cleaned up really well. Also fixing up an old topper to go on. Needs different rear hatch glass that I had out back on another truck.
