Two wheel drive or four? If you have a 4x4 and just wanting to change the rear for a test there would be no problem as long as you didn't use the 4 wheel drive. It would be a little bit of a PITA to change the rear end because you would have brake lines to deal with. Either way it is a PITA but I guess if you have a rear end to try already I guess it would be OK. But the way you ask about years that fit (and I don't know what years that fit) I would say make the decision on what ratio you want and do the gear change and hope your right.

The last year you can use is a '97. Ford changed to a metric lug pattern for the superdoody.
Mid year 92 Ford changed the length of the pinion shaft. If you use one older than mid 92 you may have to change the drive shaft. It also isn't as strong.
Single rear wheel or dually? The dually changed lug pattern in '89. The single rear wheel changed a LONG time ago.

FYI, ford never offered the 3.73's in the rearend of our trucks. You'd either have to put them in yourself or like mentioned a super duty one has different lug pattern to use. 3.73's weren't offered till 99. Unless you get lucky and find one where someone already has done a swap

I forgot that important part. The 10.25 only came in 4.10 or 3.51. There are 3.73 ring gears easily available but then the issue of gear setup enters in. 3.73 is a good ratio for our trucks as long as you don't haul heavy.

You mean 4.10 and 3.55. 3.73s came in the Sterling/Ford 10.5 on the 99 and newer trucks. You could put a 10.5 in your truck but the spring perches have to be moved and the bolt pattern is metric; so your rims won't fit. You can also put used 10.5 ring and pinion in your 10.25, that's what I did. But to make it profitable, you have to do the install yourself, a shop will likely cost $600+ just for labor.

NO...My ext cab Auto with 4:10's gets 16. My crew cab 5-speed with 3:55 gets 17.....I put 3:55 in my ext cab for a year and still only got 17.....Towing is the only real advantage to the 4:10's or disadvantage to 3:55's...
