Bottom of truck and fire wall taken back to bare metal.

Sprayed with Lizard Skin Sound deadening.

Painted with gloss black. The idea being the gloss black will shed dirt better than the Lizard Skin left raw. It seems to work well.

So I had a 4-speed PTO spacer machined by a friend and got it back today and it looks great. That means I only need s handful of things for my swap.
-4-speed output shaft nut and washer
-4-speed shift fork
-4-speed throwout bearing hub
-4-speed tcase to tranny bolts
-4-speed shifter

I also was told I need a 4-speed bearing retainer but I believe that is already on my 4-speed transmission, pictured here correct?

And the throwout bearing hub is this(shown on 3-speed)?

 

[40LandCruising]

Will the throwout bearing retainer off the 3-speed be correct for the 4-speed?

Are you referring to the input bearing retainer? They are unique to each transmission, a 3-speed input bearing retainer only works on a 3-speed.

For the throwout bearing I’d swap to the late 4-speed style, it’s a much nicer design. You’ll probably need to use a 4-speed clutch fork to go with that.

I did mean the input bearing retainer, and I’ll go with the 4-speed throwout bearing.

Is the input bearing retainer what I have pictured on the 3-speed?

This is the input bearing retainer

So I think I figured it out, I can use the throwout bearing off the 3-speed on the 4-speed transmission, it will fit over the bearing retainer, but the 4-speed throwout bearing is better.

Correct. I like how the later throwout bearings don’t have that big flat contact area. The late model 4-speed ones are a big beefy design. Bulletproof unless you wash the grease out of them with enough water crossings.

Don't throw away you're 3spd TO bearing or clutch fork. I'll throw you some dollars for them as spares...if you aren't using them.

 

[NCFJ]

Lots of 80 series doors, hoods, fenders, core supports, inner fenders, hatches, tail gates

FULL, still in the truck, brown cloth interior. CLEAN, including head liner

All this stuff is going one way or another, don't cry once they are gone. I have 3 full trucks here and I am only keeping the rollers. It either all sells soon or goes to the scrap yard, I need space back.

Send PM if interested

Also would take the F flywheel. @40LandCruising

They are both yours

 

[cruisermatt]

Why would you not run the 3-speed flywheel? They’re awesome off-road.

Because I have a 350

Very minor wrenching. 4 bolts, after some cuts, grinding and sanding and painting.

Had to modify the crusin offroad transmission skidplate to allow enough space for my ridiculous driveshaft angles......

So I just got my 80 back from the shop today. They slightly improved the brakes by replacing the master, but they still aren’t good. I know there is no air in the system at all, because almost 2gallons of fluid has been run through it by the shop and me. And the LSPV has been bled many times, and even adjusted to see if that would help. This is stumping me and slightly frustrating. It is safe enough to drive and I don’t expect perfection given it’s on 35” mud tires, but the pedal is not firm in the slightest and goes to the floor.

Also, the 80 had started running awfully when I took it to the shop. They replaced the spark plug wires which helped a little. After doing some research I thought it was my Air vane thing, but I unplugged the O2 sensors and that solved the problem. It just throws a code for the O2 sensors now. Anyone know the actual issue? I just replaced the sensors two months ago.

no real idea just guessing.
was the push rod adjusted properly on the master cylinder when it was replaced?
maybe the soft brake lines are swelling when you apply the brakes?

what brand of o2 sensor did you purchase?
make sure there isn't a rip the lower intake tube near the throttle body.

The master was installed by a reputable shop so I assume it wAs adjusted properly. And I bought NTK O2 sensors which are Who made OEM ones in 94. And I’ll have to look for a rip.

Got all the material for the a-frames for my gantry crane project cut yesterday. Thank god for plasma cutters. A horizontal bandsaw would have been nice though.
