    You’ll need to take the banter here with a grain of salt. Sometimes you get dipshitery, sometimes you get useful information. Don’t let it get to you.

    Yeah, you’ll lose 5th if that nut comes loose, so stake it into place. It’s a very common problem on 5 speed roadsters. Interesting about the reverse idler. My 4 speed clashes in reverse sometimes even when I’m stopped. One of the shafts takes a while to slow down, and it will grind for a split second as it meshes. It does it mostly when it’s cold out. Kind of annoying.

    I had a 1993, 2WD. Maybe that’s why it didn’t have one. The 4WD’s might have been different. I’d love to have another one. It’s unfortunate the body used to rot out on them, because the drivetrains lasted forever.

    Probably determined very quickly that everyone here has lip schitz.

    Wow Hainz, super informative post. 🙄 They probably don't last a year on Ratsun because of posts like this.

    Mike’s kit requires D21 hubs, not spindles. It also requires that one corner of the stock spindles gets cut off. Beebani’s brackets require D21 4wd calipers and Honda passport rotors. They bolt right on. New front lines need to be made to connect to the calipers. I agree with Crash. Rear disc is nice, but not needed.

    If you use Right Stuff gasket maker on the oil pan, lay a nice bead on the pan and let the bead skin over before putting it on. That’s how I use it on diff covers so that it doesn’t ooze into the cavity.

    If you have a granite counter top or some other nice flat surface, I like grinding sealing surfaces flat with some 400 then 800 sandpaper.

    I don't know much about the 5 speeds, but the 4 speeds had needle bearings on the lay shaft that would go bad and wreck the shaft in the process. Just something to be aware of. I'm the type of person that would just rebuild the whole damn thing because I don't want to have to take it back out later.

    See, my experience is opposite of this. The problem with SU’s is that the choke isn’t really a choke.
