I bought the 68 in 92 and it had what was left of the original interior (I think anyway).....grey vinyl, the rear benches were recovered black vinyl. So that my wife could drive the beast, I found a local mom and pop upholstery shop in Hobbs USA NM....and I was looking for something cheap....he had remnants from a couch that he just finished....kind of a green grey striped wool....
We had 2 Newfoundland dogs, 2 boys at the time and would load her up and explore the desert in Southeast NM. The wool seats are cool to sit on in the summer and warm in the winter.....never burn your leg....and never have to to wait for the heated seats to finally...get warm.
Wen I restored the rig in 2017 and 2018, we knew we wanted wool seats again, just didn’t know exactly. My wife and 22 year old daughter picked the colors and came up with the Pendleton blanket ideal....the upholstery shop we used for the restoration, came up with sewing the Pendleton tags back in.
I live in South Central WA, 100 degree summers, fairly mild but cold winters....seats are comfortable all year.
Wool isn’t for everyone....but if you have a daily driver...and looking at easy trail drives or mall crawling....it’s not a bad option.
I really never bought an FJ40 as a mall crawler. Most people never did. Or easy trail drives. It was in the sun, wet, abused by dogs , kids, etc... I went through quite a few refits on upholstery, vinyl, because of cost and durability. The only way I would use a Pendleton blanket , is if my FJ40 is retired . Not to say it is not a very nice fit, just not for tough usage. Then again , I wonder why they lace caskets with costly materials.
