I put a tank from an 85 long bed "1 ton" in my 83. holds 20 gallons. had to cut the rear saport
and move the shock from in front of the axle to the rear of the axle. and the 20 gal. tank was taller to.
had to make a spacer to lower the front mont down. and raise the bed abour .5 of an inch.
even used the EFI pump too. butt that was a bit much.
oh and it's great having more fuel on a trip.
helps to take the bed off then look at it.
