I seen this topic before but I can't find it now.
I wan't to put Kadee couplers on my SD70, USA freight cars, USA bay window caboose, and a gp7. Any ideas on what would work best. I don't plan on every having less than 10' curves.
I see you planing on using 10' curves, with 10' curves you would be better using body mounted couplers, they are a little harder to install but they look much better, they don't sag, and they allow you to back up your train...below is the URL for Kadee conversion page as to which size to use the, choice is one you have to make, the installation of either size coupler is exactly the same smaller '#1' which is the correct size for USA equipment, or the larger 'G' coupler is more for 1:22.5 or 1:20.3 scale...I model in 1:20.3 narrow gauge so I use the 'G' couplers, if I were to model in 1:32 or 1:29 scale I would us '#1" couplers because the are the correct size....

I have to second the body mount advice, my min diameter is 10' and body mounting all cars and locos made a big difference in reliability, and the length of trains.
I have mostly USAT freight cars, and the G scale 830's bolt on in 5 minutes. Do the 820's bolt on or you need a shim? I think so.
So for me the G scale was easier, and more resistant to uncoupling from vertical curves.
My advice is to look at the cars and locos you have and research the amount of effort so you are not unpleasantly surprised.
Who said G scales not fun??? heres a video with the g scale couplers. i like them better email me if youd like install pictures
Thanks for all the help. From the conversion lists I think the G scale will be easier with USA freight cars. I didn't see anything for the Caboose. Is there a body mount for that or just truck mount? Or is it too short for a body mount?
I also believe I read where someone used something other than the 836 or 831 on the SD70 but I can't seem to find it when I search.

Thanks Greg. Looks like I will be off to St Aubin for some 830's and 831's. Doing my part to help the economy LOL.
Before you go do not count out the 789 body mount coupler.
It has the same box as the 831, but it has a straight shaft coupler, it offers the MOST latitude then the 830.
Yes it will take some adjustment work adding Evergreen plastic shims but you will be happier then if you used the 830's.
Great if you run on 10' curves always...but lets say you take it to a friends house that has 8'OR smaller, the 830 do not like tight curves..yes I know they bolt right up to USA and possibly bachman..BUT you will be happier with the 789s'.
Don't let the adding shims scare you..it did me at first, but after doing a car or 2 it becomes totally easy!
I also use truck mount 831 couplers, as stated by Don Hofshier, but I use them for shorter trains, I use both the 789 and the 831. Those are one of my standards on my layout.
Backing up my trains into my storage in my garage has such an incline and it has a couple of switches and the truck mounted dont like a lot of weight to push against so the derail themselves ALWAYS, if I back up a long train.
Most if not all of my trains have 789s' on them...and a few still have 831's.
Since there are several options here, I would suggest trying both on a few cars... If you lived nearby I could give you a few 831's...
Seriously the comment Bubba made about backing up truck mounts is also an important item. I wanted to do a lot of switching and operations, so backing long trains happens. I have friends that love their truck mounts, and Bubba is right that there are differences in swing between the 2 types proposed for body mounts.
Also, people do modify 830's on occasion for more swing, but then that is balanced by ease of installation, etc.
I just put kadee 820's on the USA wood chip car. Took a few minutes, mostly for the paint on the shims to dry. I used an 830 box to size the plate (USA provides holes in the underframe) then I put the 820 on the shim. Used a kadee guage for height and it works fine.
Body mounts look and act great. They aren't that hard to install. By about the third car, they went on pretty quickly.
