1975 GMC Palm Beach Restomod

Projects for today: remove and replace calipers, install cooler for steering/hydroboost, install transmission temp sensor.

I had to rework the plumbing a bit for the transmission temperature sensor. The probe on it was much longer than I anticipated, so I had to use a brass tee fitting in order for it to fit.

What did you do to get your garage floor looking like that? Pretty slick.
It is acid stain, and I don't recommend it. It would be fine if the garage was just for parking cars in, but if you are going to do any work in it at all, it isn't great. It shows a ton of scratches and needs to be waxed a few times per year to stay nice. I may epoxy over it eventually, although epoxy doesn't hold up to welding so I don't know.
 
CTS-V 850 watt brushless fan mounted to custom shroud on Griffen GMC aluminum radiator.

Nice work Mike! I’d like to get my hands on that fan if I can find a high output v-belt alternator that will fit.

Also , did you happen to look into the lower outlet on the Griffin radiator? We’re you concerned with flow blockage from the trans cooler? It covers most the area of the outlet.
I have a new uninstalled unit out of a parts coach I bought and just noticed that and was second guessing the install.

Wow, lots to say.
First, as the proud driver of a '73, did you know my coach is powered by twisted rubber bands? 455 of them, of course, because we need the torque. That's pretty much the comparison of my coach to yours. I'll send you engineering specs and drawings if you're jealous.
Secondly, just what is a "Air Gen IV Magnum." Is that somehow related to dash air? I've always wondered what "dash air" referred to. Some kind of venty thing perhaps.

Thirdly, I do have kudos for your capacity conclusions.
On a trip from Chicago through Detroit and up along the St. Lawrence Seaway to the ocean we found ourselves repeatedly meeting a 36 foot Bounder pulling a trailer with a Harley on it. After several meetings and (mis)adventures together we were momentary friends. Later, by chance, we meet for the last time at a picnic table on Prince Edward Island, they on the Harley, we in our GMC.

Munching our lunch they delivered a short observation on their experience. They said, and I quote, "We had some really good times with our friends, but eventually we'd had every conversation, played every card game, judged and rejudged every decision we'd made in our marriages, so we finally said to them, take our RV and head home, whichever route you want, we're on the Harley."

We nodded politely at this somewhat too intimate saga. Then came the nugget of wisdom as they said: "No matter what the length, or supposed capacity... they only sleep two."
Words to live by, we thought at the time.
We don't have kids/grandkids so the conclusion is speculative. But, so far, we find it true.

Brilliant rehab on your coach, by the way. I wish I had both the money and imagination to do such marvelous mods. You Rock.

I don't think it will be a issue. There seems like there is enough depth to flow plenty of coolant through the outlet. If it was just an outlet that relied on gravity, I'd have a little concern, but since the fluid is under pressure, I think it will flow fine. I guess I'll find out soon enough.

Thanks. The "Air Gen IV Magnum" is actually "Vintage Air Gen IV Magnum". Vintage Air is the company. They are based in San Antonio and are basically the hot rod industry standard for aftermarket air conditioning units for older cars and trucks. The "Gen IV Magnum" is their newest and highest capacity unit. It is indeed a replacement for the factory dash HVAC.

I agree on the radiator, I’ll give it a shot.

Let me know if you paid attention to the torsion bar orientation before you removed them... I’m rebuilding my front suspension and just took it all apart and forgot to mark which flat on the key is supposed to go to which flat on the control arm socket... ? It might be a trial and error fix.

I did mark the torsion bars so they could be put back exactly how they came out.

Nice, do you mind snapping a pic or letting me know the arrangement next time you’re out there looking at it? If it helps, I’ll work up a diagram with labels to make it easier to match up...

I just marked the top of the bar with a paint pen and then later scratched a mark so I would orient the same way going back in. The end of the tube is marked left and right.

cool that’s half the problem, if you chase that X back to the key, which number does it align to - see my pic , (assuming a straight line back, no twist )

I didn't mark the pork chops because the book says to position the pork chops where the end of the arm will be 1-3/4 - 2" below the crossmember. On the stock pork chop with only 6 positions, it should be fairly obvious when the are in correctly.

Side note: Since I pulled my subframe forward to remove it; I did not have to loosen the crossmember to remove the torsion bars.
 
I’ll take, “things I hope to never have to do again for the rest of my life for $1000 Alex.”

I got the cockpit area subfloor step done. What a PITA. Each board had multiple grooves cut out of it at various depths and widths. The horizontal piece was just ridiculous. 3/4s of the material was routed out on a large part of it. It took me almost a full day just to do that piece. Plus, I had to go upgrade my router to something a little more hefty.

i’m going to seal it with Epoxy resin and hopefully reinstall it all this weekend.
