So.... I bought a 8/71 (72 model year I believe, gotta get paperwork squared away). I have a few questions. Hopefully some people want to share their knowledge. It's a 1310, does that mean it's a dually or? Right now it has some 19.5 rims on the rear and the split rims on the front. I assume this is not stock. The short stepside I'm unsure if it's stock ? We're 1310s built with a conventional bed step or fleet? Has a 304 and a stick shift. Not sure if it's a 4 or 5 speed (doubtful) Is there a tag on rearend for gear ratio? Has two gas tanks with a gas hole in each fender,. Very weird. Is there any cool gas caps that are flat and say IH on them? My goal for this truck is to use it as a truck and it has a fifth wheel hitch in the back of the bed. I have a f550 Hodges car hauler but I do get random phone calls to do 5th wheels. I am going to put a 7.3idi 5 speed in it. Looking for donor truck now.
