I agree with poster above but I wouldn't do RHD.
You won't maximize the value of your restoration time and investment. I can source Colombian LHD 83 FJ40s that are rust free and driving but the (good) condition is such that they would be $20,000 to $25,000 minimum price in Florida by the time I got them to Florida. I have not offered these because in my case it makes more sense for me to restore them in Colombia and bring them up to a $30,000 to $35,000 clean FJ40 in around 30 days or $50,000 to $60,000 frame off in about 90 to 120 days. Most of the low priced 83 FJ40s I have seen for sale in the US are "some rust" (in my eyes very rusty) and are asking $20,000 to $25,000. This is all in my humble opinion.
If you are interested PM me. I bring the trucks into Tampa and put Florida tags on them. I have 2 1983 FJ40s that I know are available right now.
Most estimates say the numbers on US FJ40s per year are roughly...
70's models around 10,000 per year
1981 I think 1000 came in
1982 around 700
1983 around 300
There is a big jump in resale value on the 81s and 82s and then especially the 1983 model over the mid to late 70s models due to those numbers above.
Colombia, Japan, Australia etc had 1984 models too.
Recent sales at auction for frame off Colombian spec 1983 FJ40s have been upper $50,000 which is in line with the US spec ones given the same condition.
Here is my 1983 FJ40 frame off I did a year ago. Also the metal tops like this one are rare in Colombia. most come with a fiberglass top or we do the traditional soft top on them.
Lazaro is on the right track however if he considering to do a full frame off restoration. Makes more sense to do that on a 1981 or up FJ40 (or better yet a FJ43). If you are trying to do an affordable truck buy the BEST truck you can find regardless of model year and stay away from restoration.
