4 speed is out. I think I’m going to pull all gas and brakes lines to zinc. Along with the e brake stuff.

I own the system. Looks like some countries call it wet blasting. I think the term vapor is very appropriate. It produces a vapor when it’s going.

Well old diff is out. Half shafts are being a paint and not coming off easily. I need a lift. Sadly I need a new house for the lift:)

More then just a pressure washer. Air pushes the slurry. So it’s a sort of mix between sand blasting and pressure washing with mini glass beads

Vapor is worth it. But so labor intensive on such a large dirty part. Also not then best casting.l, which makes cleaning take longer. Now it shows finger prints. Glass and sand blasting would hurt the surface.

I got the 5 speed close ratio transmission case vapor blasted. Took forever, like most of a day. Looks good though

5 speed is mostly apart. Really all I needed was a long puller.

Here is a good source for new r180 shims. https://parts.eastsidesubaru.com/productSearch.aspx?searchTerm=SHIM-BEARING They have all the sizes.

Starting to take the trans apart. Curious if I can getting bearings on and off without a press.

Well results are awesome. I couldn’t be happier. All mating surfaces are free of powder and ready to be put back together

Powder coating masking is the worse, it's this terrible rigid tape. It works, but not nearly as well as this. If you can sacrifice something to do a firm mask off, it will turn out awesome. This is just my experience in years of powder coating car parts. I am sure there are other ways. My powder shop charges me a lot less if I do the prep/ masking.

Powder can't go some places and it sucks to remove. The more time I spend prepping the better. The surface has to have zero grease or it ruins the powder coating. This is just a easy method to make sure it comes out nice. They do the same thing with engine blocks.

I will look into the driveline stuff more. Diff is prepped for powder coating. Inside is clean and empty. I sealed it to minimize sand and powder getting in. I will then burn the powder off the aluminum parts and then wire wheel smooth and vapor blast to look perfect.

Anyone know what to do about a drive line? Since the 5 speed is shorter then my 4 speed.

I think they said it was new. Zgarage is testing it this week.

I have decided to do the 5 speed swap. A fellow z guy had a hoard of parts and hooked me up with a close ratio 5 speed and a later R-180. R180 will be 4.11 gears and OSGiken LSD. Trans will be rebuilt, vapor blasted, then all steel parts will be zinc, powder or professionally painted. Rear end will be powdercoated 60% gloss black, then all steel will be zinc coated. Should look super nice. I am also building a nice crate, which will hold all of my rebuilt original parts, in case I ever want to sell and go back to stock. I am trying to decide on a clutch/ flywheel combo. OSGiken Single clutch unit looks nice and streetable. I am having fun. I am convinced that dirty parts look the best later on. Since the grease protects them.

First start after a long cold couple months.

The heat shield on my 71 series 1 was clear cadium . That was from my zinc shop that had a harder time removing it.

I have been zinc plating for a few years, I have used 3 shops, sadly I have zero local options. I ship via priority mail. Usually comes back in a week or two. Whatever shop it is, chat with them about prep. My current shop wants pretty minimal prep unless it's painted or rusty. Also will they do small batches? I prefer smaller batches for say 50-75$.

I have a 77 bronco:)

Well I had to pull the hatch vent cover to get to the some of the parts for zinc. The cork had turned to the oddest goo/ glue. Anyone have a foam seal they used for this spot? Needs to be thin 1/8th? Also the tiny brackets for the vent had paint coming off so I had them powder coated. Should outlast the z body:) Only a tiny bit of surface rust in the vent area. I am thinking about converting the rust and doing cavity wax. Thoughts?

Well they work! I need to tune their tone, it's kind of an odd mix of old and new.

I will have to find the thread. I’m not restoring mine. But just making it nicer. Someday I might acid bath it and paint it right. Who knows.

Original wiring harness sticker. This was up by the horns. Pretty neat to find after so many years.
