Nice find Dallas.
My fixed top Fj45 had sat for 23 years, and full of hornets as well! I did get the 327 to fire up, and drove it for a couple of years, but the fouling of plugs meant weekly plug changes.
My fixed top also has the screw holes for the vinyl rear top piece. I've always thought that's where the PO attached the 1" long shag carpet. Good to know that something actually went in there. I'm about to upholster the interior and this does give me some ideas.
Is the bezel embossed? Did somebody already pilfer it or is it not showing through? I could never get my bezel to show Landcruiser until I painted it.
I agree on upgrading the brakes. You have my permission to also do power steering. I don't think these or your other modifications are bad, but I'm no purist either. I don't see why some people think that even adding bug splat to the windscreen is soooo horrible.
I would also suggest upgrading the 12V generator to an alternator if it's not already been done.
You're not going to do anything to it that cannot be undone and simply improving the driveability so you will have much more enjoyment in the long run imho.
That being said, I have plenty of spares if you find you need anything, like Husky hubs, and "claw" axles.
One thing about the lift is that the rear springs are special. I believe you will need FJ40 fronts, and FJ55 rear pieces. Same with rebuilding the brakes. They don't use FJ40 parts in the rear axle. Possibly some of the proportioning valve issues could be due to this size difference in the slaves.
Does it have the coil overload springs still on top of the rear axle?
Be careful opening the passenger door in the wind. I don't think there was enough metal left to bond to the door. When I've had to fix these I've added strap down the door for strength and made new "loops".
The tire carrier was an addition. Looks like they relocated the tail lights to make it work.
