All that aside, don't overlook the 69-75 models. The only "real" difference is the drum front axle and that is easily and cheaply fixed by a simple mini truck front disc swap. Also, the earlier models arguably have better sheet metal and resist rust somewhat better. One other advantage to the earlier "three speed" trucks is lower t-case gearing which is nice off road. My best advise would be to shop all years after 69 but hold back a couple hundred for the pre75's so you can do the disc swap. Finally, the 2F engine (74 and later I believe) has better oiling and a bit more power. Don't get me wrong, the F is a fine motor also but not quite as refined as the 2F. Just my $.02.  |
Having had 8 FJ40's from '63 onwards, I know that none of mine had as low gearing as my '74 w/4spd due to the compound low installed. However, the 3spd in 1st gear, even with the 2.313:1 is still not quite as low...the lower first gear (3.55:1 minimum some higher), coupled with the 1.99:1 xfer gives you a lower final crawl ratio. Also, the synchronized gears are nice indeed. Your final crawl ratio is the product of your tranny gear X xfer gear X differential...so basically, if you are comparing trucks that all have 4.11 gears, then whichever has the highest product of 1st gear TIMES the Xfer low range ratio has the highest crawl ratio. An interesting table can be found here:

I agree 100% on the metal. My 63 FJ40 and my 45 pickup were tanks...could walk on the hood!
I also found the 2F to be a plus, more torque at LOWER RPMs...the only thing I really miss from time to time about the old (really old) F's (no, NOT the oil lines) is the Oil Bath Air cleaners...those were sweet...Even the valve cover on the 2F is better...oiling too.
I opted for 1978 myself, what I wanted, what I bought. Again, it comes down to what you want and what you like and of course what your plans are.
Side note: You can really get some crawl AND traction (even with open diff) in the 4spd models going uphill in REVERSE!!! LMAO...seriously...try it...
Also, note that the NON USA FJ55's from 69-71 (5.299:1 1st gear AND 2.313:1 xfer = Sweet pig)
