Sorry you are in that position- I really hate dishonest people-
Anyway, from my limited knowlege here's my take-
The 3100 is more desireable/collectable and thus probably worth more in value. But, I personally like the 3/4 ton better- I like the look of the longer wheel base. I also like the fact that it was easier to put a standard replacement open drive rear end on with newer brakes (I used and S-10 with 3.42), and easy to put a 1/2 ton front axle and new disc brake kit. This gave me 5 or 6 lug wheels (depending on the rear you use). Most other parts are interchangable with the 3100. I have had no trouble finding parts I need- most of the reproduction places have 3/4 ton stuff.
I'm sure others will chime in with varying opinions, but that's mine.
Too bad there are so many scheisters in this world. I bet once you are into this project you will be happy with your 3600.
Best of luck!!!!
