On TF trucks the 3100 (short bed) and 3200 (long bed) use different size brake lines, front hoses and front wheel cylinders. I believe the rear wheel cylinders and the hard line on the rear axle are the same for both though. I've been able to find both at Napa.
The 3200 is a med. bed of sorts not the longest bed (they made 3 sizes in 56). They tell me the lines, wheel cylinders and shoes are all the same between the 3200 and 3100.
Either way the 3200 lists the wrong parts.
The 3200 uses different brake components that the 3100 for the hydraulics. The only directly interchangeable parts are the master cylinder, drums, shoes, and wheel bearings/seals. The rest is the same as 3600, including the lines (1/4" vs 3/16" ). The front hoses from a 3100 can be used on a 3200/3600, only difference is the length, fitting sizes are the same.
I'm not sure that's the case. The hoses for the 3100 and 3200 are the same part number at Napa (doesn't fit).
Bad news is the part that attaches to the frame has a single circlip and isn't threaded. Original hose on mine is threaded and fits the hole in the frame and a nut secures the whole thing from the inside of the frame then the inner part of the fitting is threaded female for the brake line's flare nut to screw into.
They had to match my old hose to get another one.
I'm not really sure how the style they list fits. With a single circlip nothing is there to hold it to the frame.
I was also told by an old timer awhile back that if they ran out of parts for certain model at the factory they would use whatever they had on hand. A 3600 could have 3100 hoses on it. Not sure?
The replacement hose I got they matched is stamped 1/8 on the outside. It's a little narrower than the original. Hope it's not an issue and the inside diameter is correct.
