I am looking at late 60's to 70's 1 ton to 1.5 ton IH trucks for purchase. Most are 2wd flat beds. I am a 100% disabled veteran and I only have part of the muscles and the nerves are all messed up in my right leg. I am on my 5th knee replacement, so with most trucks being standard tranny, I need to switch to automatic. My uncle is going to do it for me, as my neck is fused, and left hand partially paralyzed. Working from up top isn't as bad, but from under neath is really bad. What will fit a 345 V8? Would a 700R4 fit? I have a very small 5 acre farm that i mess with to keep me going. It is an 1880's farmstead, and we had a 72 IH truck when I was a kid, so I have to have one. I am also going to be getting a 40's or 50's for my wife. My uncle is going to build it. He is in his 70's but still builds cars. Thank you
