We did put a MICO on one of the wreckers way back. This damn StupidDuty Ford truck with 7.3 and manual transmission, had the driveshaft park brake. Some bolts sheered off back there, and we never had time to fix it and bossman checked on parts and it was not cheap to fix. I want to say like $600 for everything we'd have to replace to fix that drum brake. So bossman cut a stick to put between the seat and brake pedal and that was our park brake, while I've got the rpm idled up and PTO engaged on a manual trans in N truck that weighed plenty and then hooking up to a car or truck that weighed more, and I'm on a slope on the freeway hooking a car with that bull$h1t ass stick protecting my life or a serious rollaway accident. That was my last tow in that truck. I took it to bossman and I said, gimme my phukin rollback back and shove this POS up your ass, I'm not driving it anymore. Phukin redneck azz BS wooden stick for a park brake? Hell NO. This isn't professional and damn sure not safe. You can at least put a MICO brake on the truck so we can them drop some wheel chocks. He's all about, Well, then WTH is a MICO brake? I asked, you really don't know? No I don't what is it? I said it's a 2x4 about 4 foot long, and get a long bolt and mount it to the side of the truck. So when you reach out the window,, you pull that 2x4, it hits the rear tire and now the truck won't move. PFFFT, LMAO !!! He was like HUH? Cuz I was pist at first, I wasn't in no joking mood, but when he asked like he was really concerned, I came up with the 2x4 BS. So after I couldn't hold the laugh back anymore, I told him what a mico brake is. Found on construction equipment usually, but some safety devices on vehicles too and if you dont' want to fix the drum driveshaft brake, it works like having a monkey in the truck holding their foot on the brake pedal. I took off in the my rollback, did several tows that day and when I got back to the yard to turn in paperwork and money, he was just finishing up and test the MICO brake he went and bought and put on the truck. I was actually proud of that cheap Phuk that day. He thanked me for the idea and said he had no idea of such a thing and it was only $225 for the kit he bought. Easy to install, and far cheaper than the $600 to fiz the driveshaft brake. I did tell him now you know I feel safe as hell with this, but IT IS NOT LEGAL. So I had to explain why blah blah blah, and he said, we'll use this in conjuction with our landscape timber cut offs we use for blocking in the tow bidness to chock the wheels as a secondary. I said good enough. I'll drive it now, Thank You, Sorry for an azzhole but that wasn't safe at all before. So it was alll good. I kept my job and didn't quit or get fired. MICO saved the day.
I had a line lock on one of my old Dodge P/U's. Needed it for that poor slant six tryin to do a peg legger.

you know if you leave the roof on that,...you could have a "covered bridge", with railings.
The roof is trashed, holes for vents, AC units etc, and it got leaks. You may notice the left rear that Luan wood is rotted away from the outside, under the fibreglass skin that I peeled off. That started in a few other places from the roof leaks where someone robbed the AC units. That left rear window leaked too I'm assuming since I see caulking on it. Or, it was the roof leaking which is what I really thought it was, and they THOUGHT it was the window so they added some caulk. The floor is weak in a few places too. I did think about even using the RV floor. But naww, I just cut some 4 foot 2x8s or 2x10s and bolt them to the frame rails and then build a hand rail on both sides, cuz this ravine is as deep as 30 feet in some places and I don't want anyone falling off.

I'm surprised that even worked to get the crooked six to do a peg legger one tire fryer. But yep, Link lock is very similar or like a MICO lock. Same principle for sure. Just a solenoid that engages pressure to the master. Some of the MICO use the existing master cylinder I do believe, that would be like a Line Lock, and then some use a divorced master like one of my buses do with the handi lift.

Not as of yet, it's the wooded part of the property on the far North side. Due to all the trees kinda dark in there but I can prolly figure something out. I think I have 1 high dollar phone that does good low light video.

I have a parking drum 413/727/Spicer 70 in the 60s Dodge M400 based motorcoach. And a parking drum equipped 350/SM465/Spicer 70 in the 1985 C60 lineman’s truck.

Both are supposed to be donating engine/transmission into vintage 1/2t trucks…
