    I know you need to machine the case, buy the bigger bearing and the corect shaft . just wondering who has done it, what the cost was, and how you like it...Brian

    Brian, There is something on this in the article on the "ORD Home Page" about the doublers. I think it is buried in a sub article about custom doublers or some thing like that. I know that he does the oversized bores in his shop anyway. I'll look for it later.

    What year did trucks come with TH 350s and NP 205s? I thought all TH 350s had 203s or 208s behind them.

    Brian, Look at the NP205 Tech Update on the ORD Hme page, most of what you want is there. Also look at the Ford Doubler article under "Custom Rotations and Hybrids" (this section is a little hard to find) Stephen brings out a lot of information in these articles.

    you should contact Stephen at ORD, we do everything in the shop, have all the parts, and can fix you up in no time!! The pricing is what you need to talk to Stephen about though. Jon

    I converted a sm465 version and have a friend who did a th350 version. The machining cost $40, the bearing was $38 and the shaft was $115.

    Pretty simple to do. Took it apart and put it back together using the diagrams in a Chilton manual.

    I did a 465 205 only difference in mine is the machining cost 60 bucks. Not difficult at all I also ground my shift rails so I could have front wheel low while I was at it.

    I thought I was wrong once,
    but I was mistaken

    when you say shaft do you mean input gear?

    part numbers and where you got parts would be helpful
    thanks

    205 behind a TH350 was always an option on a special order truck made between 73 and 79, In 80 the 203 was dropped and ALL trucks had the 205 regardless of the tranny option. This was a slip yoke version so not quite as desirable as the previous models but can be converted to a fixed yoke with parts off the older 205. 81 is when the 208's strated to come in. In 74 the 203 could be had behind a 465 but VERY rare and now very sought after to put a doubler behind the 465. In the 80's you could get a 205 with a 32 spline behind the 465 and agian the extra splines make it desirable and them convert it to fixed yoke.
    Most 72's that had the TH350 had 205's. Before that they used a Dana 20 case. In 72 if you got the saginaw manual 3 speed you still got the 20.
    So as you can see a TH350 205 is pretty rare and most people know how sought after they are and the price is not cheap. However if you look for a post about a guy asking about fair price for one I left a link to a TH350/205 combo for sale in MO for $300 out of a 72.
    I'm about to give up finding one near me and convert to a 465/205 combo when I find onefor the right price. So far the best price I have been quoted is $400 for the combo at a yard I deal with but I don't know if that is a 10 spline model. It is a slip yoke so I would need to convert it to fixed.

    $130cdn for a chev205
    this is a fair price here i cant imagine anyone paying more as these are the most common 4x4 parts on the planet.

    Just to throw a wrench in the application works, I have a friend with a '69 K5 with a TH350 and 205 in it. I don't think the truck had ever been molested.

    Well we are talking about GM here. Probably a late 69 just before the 70's came out. My bud has a 72 that came with a 20. GM did weird stuff like that forever. I find weird stuff on my late 75. In 76 was a drum width change. Mine has 76 spec brakes. There are people who say they have 82's with 12 bolts in the back.

    Several parts catalogs list 12 bolts occuring in light trucks to 85. My granddad's 84 has weatherpack connectors on the taillight harness, but nowhere else. So far I haven't found any oddities on my 85 (except the 84 grille and trim, but I put it there)

    I was just asking becuase I was curious. I don't have a TH 350.

    I wanted a manual tranny though and I wanted a fixed yoke transfer case, so the 700R4/NP 208 is coming out and the 465/205 is going in. I payed $150 for both and they work flawlessly.
