Difference in OBS F350 vs F450

I am currently trying to add another 7.3 to my stable. There is a 1997 F450 DRW flatbed close to me for a decent price. Are there any major differences in the 450 from the 350? Most aftermarket products like exhaust list up to 350 and no 450. Will I have problems finding aftermarket parts? Will my scanner work? Stuuf like that. Any help greatly appreciated.

Well for one I don't think you will find one 4x4 lol but yes the rear axle is narrower the frame is narrower and it was a cab and chassis truck so no bed from the fastory. As far as I know a 350 exhaust should work other than length because your frame most likely is also longer. It is the same motor though so your scan tool should work if it works on other powerstrokes. What are you looking to use it for?

I would like to tow a cattle trailer. I was working on a 350 cab and chassis but it appears that it was a stolen vehicle. The 450 is also a manual which appeals to me for towing.

Just a FYI. As far as I know, no one makes an exhaust system for a cab-n-chassis(F350 or F-superduty)

Like other have stated

F-superduty
10 lug axles
Solid I beam front axle with left springs
Rear axle is Dana 80 with disk brakes and 3" wide leaf springs with CAST spring hangers
ONLY came from Ford in 2wd but they area FEW conversions out there
Drum parking brake on back of trans
Hydroboost brakes
15k GVW
137" or 161" wheel base
diesel or 460 engine choices

F350 Cab-n-chassis
8 lug axles
TIB(twin Independent beam) front axle with coils
Rear is a Sterling 10.25(drum brakes) and 2.25" rear leaf springs with stamped steel hangers
Came in 2wd AND 4wd(4wds had dana60 Solid axle and leaf springs)
11k gvw
137" or 161" wheel base
351, 460 or diesel choice

And YES your scanner and every sensor is the same between the two trucks
