I “think” it’s a 4 speed but I can’t seem to match up the bolt holes on my ‘75 FJ40. Maybe I gave up too quickly. Your thoughts are welcome .
Help identify which style this skid plate is…. 3 speed or 4 speed (27 Viewers)

Three speed. If the back two sets of holes for the revit and bolt match it for a four speed or five speed.

I know my 73 has four sets of fixed nuts on each side rail. Both fill three and four speed skid plates will bolt up. How long Toyota continued with four bolts not sure. If your 75 has four sets it will bolt up using the front three holes. How that will line up with the transmission and transfer I'm not sure.

Thank you….there are 4 holes in the frame so I’ll get back under it again tomorrow and try to get it matched up. I do think though that the 1” 90* lip on the back is going to interfere with the transfer case… I’ll get back and confirm
That skid plate looks nothing like the one on my 01/72 build with floor shift 3-speed. The microfiche only shows three different p/n's for the FJ40 series for the period from 03/69 to 07/80.

Hmmm… I didn’t have the greatest method of trying to line it up. My upper body strength wouldn’t engage as easily as I’d thought so tomorrow I’ll use a floor jack and position it better. It got heavy real quick after I didn’t get the holes lined up on the first tries.

The part number that ends in 11 is the only one they show for a three speed. The one that ends in 30 is the four speed up to 1/79. 31 is 1/79-7/80 four speed. Change over from. Three speed to four speed depends on the market. US is seems to be 1/74. Some markets had the three speed thru the 82 model. The three part number for the three speed was still the one that ended in 11 1/75-1/79. 1/79-7/80 part number ended in 12.
Believe the skid plate on the left is 1/79-7/80. Center is 8/80+ four speed. Right skid plate is 10/82 on five speed. The holes for rivets and bolt all match.
What I have done is the past is put a box on one side on put one side of the skid plate on the box. Then go over to the other and left the skid and start a couple of boxes. I also have a Harbor Freight transmission scissor jack. Has it a long time, only only $40. Great for installing and removing Bull Bars, sliders, fuel tanks and skid plates.

This is great information….thank you for setting this in motion. Going out there shortly to see where it lies… looks like mine is different…quite possible that the typical inward bow from it doing it’s job in a previous life is contributing to my mounting difficulty. Could be “hammer time”.
Unless there is a better way. I’m thinking my log splitter and its’ 50 ton hydraulic cylinder has a place in this

Back in 82 some of the plate nuts were bad that held up the skid plate. I tapped them all out to the next larger size then bought stainless steel allen bolts and large area washers.

Hey Charlie, I did chase them with a tap and I have all stainless hardware to replace the bolts with. Surprisingly, they were pretty darn clean…except that one! as always
IMHO almost every fastener needs either anti seize compound or threadlocker.

Here’s a question I have had for years…. Is anti-seize used on lug nuts?
I do (lightly) so they don't rust on. 60 of driving have never had a properly torque lug nut come loose.

When I did this
It also bashed the skid plate against transfer case. Used crowbar and scissors jack to get clearance from the transfer case. If you install a skid plate upside-down with a solid spacer and longer bolts you can use a floor jack to bend back in place. Sure a two ton jack can get the job done.
