Had to test the trailer brakes last night so I brought the SWB in to the shop. I'm going to switch the rear disks from the LV over to the SWB. The LV needs to stay all Toyota and the SWB needs better braking with a planned upcoming engine swap.

I'm thinking either 5.3 or 6.0 depending on which falls into place when I'm ready to do it.

Which will be about 20 minutes after I sell the LV.
 
drove it a bit yesterday and this morning. I was driving into the shop and it felt like the rear brakes locked up. I stuck it in low and got it off the road. Called the wife and got a ride to the Tundra. Trailered the 45 to the shop and found the problem.

or did the collapable preload spacer fail? Details..
 
The details are I swapped the drums from the SWB to the LV and put the disks from the LV on the SWB.

Had to pull the axles to get the backing plates on.

Used it as a teaching moment to show the kids how a diff works. Had one of my advanced kids put the cover back on and button it up. He forgot the last step.

I had another teaching moment today.

The flange had completely welded itself to the inner front bearing race. I couldn't get then apart with a sledge and a big vise.

The LSD looks ok other than the new pattern on the case. the ring has a couple chunks out of it. The pinion is destroyed. The gear is missing chunks. The shaft is trashed.

I tossed a spare open diff in and drove it home in front wheel drive. I have to go get a rectangular pattern driveshaft flange tonight from a buddy. The one that was in the diff was square. The LSD is a carrier type so I have to take everything all apart and set it all back up again. I didn't need to do that today.

Picked up a fine spline diff from aforementioned buddy last week. He didnt have a rectangular flange with a coarse spline, but he had a whole diff with the right flange on a fine spline. Today I swapped in the LSD to the new diff and stuck it in the 45. Good to have rear wheel drive again.
 
Rebuilt a quadrajet to replace the carter comp series afb. I like quadrajets. They work better especially with Chebbies. Got it sorted this morning. Runs much better at lower speeds. Should get better mileage too.

Got a bikini top. Waffling between running it all the time or just when it rains.

Got a weird problem with the rear brakes. The further I drive it the more they drag. I'm thinking it might be a residual valve issue since it never did it with the drums. Wildwood adjustable prop valve be here tomorrow.

Pulled the brass plug in the master and there was no residual valve. I checked the rod between the master and booster. It's not adjustable. I adjusted the free play at the clevis at the brake pedal. That seemed to help.

The quadrajunk is the s***. It runs so much better. It might get me to stop looking for 5.3 liters.

Prop valve showed up but I didn't put in on today.
 
Still applies the rear brake, but takes longer with the added free play.

I'll have to sort it out next week.

The steering wheel that's on it is from the LV. The LV needs its steering wheel back. The PO cut the center section out of the SWB wheel and had welded it to a Momo flange. I have a bunch of later LC wheels so today I had the center cut out of the best of them. Next week I'll turn down the stock splined section on the lathe to fit the new hole and weld them together.

Is the center of the wheel weldable metal? I ass-umed it was some kinda injection molded zamak alloy...

Dunno. Its ferrous. We tested it with a magnet. I suppose I should experiment with a spare wheel first.

If not I can make it a press fit and tap it for set screws.
 
It welds, but I can't get it hot enough for good penetration without melting the plastic. I'm going to try to drill it, but I might have a lead on a real one.

I'm sure it's ferrous because I got a chip in my eye and plucked it out with the magnet on my pocket screwdriver.
 
Finally got the carb dialed in. The Vortec heads, mild cam and vette headers apparently flow better than a 1975 Camaro. I took the main jets up one step to .078 and the metering rods down two steps to .042/.026 and the stumble is barely there when cold and gone completely when warm. I might be able to get away with another step up in main jets, but I'm pretty happy now.

Now I just have to try and keep my foot out of it.
