i'm doing a cab swap on my 91 and the donor cab i'm using is a 2wd auto so i have to gear up a clutch and clutch master. how hard is it to set up? i've never done and clutch work so i don't know much about the system. Anyone with expirance would be great.

I'll just paste my response & info i have, also why don't u use the clutch parts from your old cab?
PARTS U NEED:
1.Tranny & Tranfer
2.Clutch pedal assy.
3.Clutch master cyl, slave cyl and hard&flex line
4.Shifter surround for inside the cab
You'll have to take good measurements from the donor truck to get the holes in the firewall right for mounting
the clutch master cyl.
I don't remember what size bi-metel hole saw you need,maybe someone else does.
You need to cut a longer opening in the floor for the shifters.
You don't need another ECU and you're drive shafts will fit fine.
All autos i've seen have had a gear ratio of 4:30 and factory 5-speeds have 4:10s.
You'll also have to fix the wiring harnees so the truck will still start.
Now in the big group of plugs that hook to the auto theres a white round one that has three wires,
two big wires and one small.You have to wire the two big ones together.
On mine i threw the auto in the junkyard so i cut the half off the tranny(leaving a few inches of wire on it)wired
the big ones
together cut the small one off and pluged it back into the truck,works great.You have to becareful though because
the truck will try to start whether the clutch is in or not.

the truck will try to start whether the clutch is in or not. EVERYTHING WHAT HE SAID you will also need the flywheel pilot bearing flexplate cover from the donor rig. get a shifter boot and cut the floor corisoningly to the base plate..or do what i did and cut the tranny hump out of the donor cab and rivet it onto the existing floor boards. the wire is the big black and black with white strip...you can also run those wires up the the clutch switch so it wont start in nuetral...also you will see that the harness from the 4wd auto comes apart for the tranny and transfercase..the transfercase harness will plug right in to the 4wd 5speed transfercase connector.you can make the crossmember from the auto work but if you have a donor rig just take the crossmemberand mount from that... you will need to drill a 1" hole through the firewall but bolt the brake/clutch assembly up first to mare the hole first. Its super easy to do the swap and it only took me an afternoon to pull the auto out and pull the 5speed out and install the 5speed in the good truck.

I'm resurrecting this one to ask about the same drill on an 87 'Runner using an 83 4x4 as the donor. I'm mostly worried about driveshafts. Should I just get out the tape?? Any issues using the 83 5spd and case?? Thx

I have an 83 tranny & tcase in my 84 runner......
Obviously the tranny to motor is fine (mine was manual to manual) but the tranny is a bit shorter... I welded a new plate for the front most bolts on the crossmember and the rear bolted to the orig front....
Use the 83 front drive shaft - may need to drill or swap flanges. Rear if memory servs i'm using the 83 as well - I did have some DS work done but it might of been the joints....
Now for the fronts... I'm pretty sure you can use half the 83 and half the 84+..... if you compare side by side you gotta use the main shorter side (I think this is the main shaft not the slip side)...

TRC has most of the 83 stuff covered. The specs for the L-series is in our Toyota FAQ above.
HOWEVER, if you are looking to really build this truck, an R-series tranny would better suit your needs, and I don't think you'd have the crossmember headache with the shorter L-series tranny.
