Ir is rare for sure. How rare is hard to say, but this is not your common 1976 Ford F100.
Yes, but it only has 105 hp from the 1982 f100.
1953 Ford F100, according to IMCDB.
A 1978 Ford F100 Custom 1/2 ton pickup LWB with no AC sold new for $5179.
235/75/15 is the size on my 1966 f100
Great site for that. http://www.fordification.com/bodybuilder70.htm Has dmensions for all the variations.
In some 1982 Ford f100 trucks I know they have a 4.10 Gear ratio like my truck but with that gear ratio if you go over 55 mph you can say goodbye to your gas mileage so get a smaller gear ratio.
The vin plate on a 1955 ford pickup is located on the inside of the glove box door. it is riveted into the back edge of the door so if your glove box door is gone you will be out of luck on that truck.
I have a 1970 F100 and it has two lap belts that look original. I don't know if it ever had one in the middle, but I doubt it.
