Sweet I like OEM parts upgrades! Mine are getting rusty anyway.
Yeah, I brought this up recently, since i was planning to do it.. but after a few responses stated the wiper arms may run into the hood while up, I’m not sure I want to do it anymore. I certainly don’t need any worse paint..!

On another note... my damn backrest heater went out this am. I had an idea it was going, because the last week or so, it’s been EXTRA hot.. so it hasn’t blown any fuse, but pretty clearly the wires are fried. I use this thing almost every time I drive. Gonna suck w/o it. POS back....

Anyone have a part number handy..? I needed to redo the bottom of my seat already, and have the leather and foam for that part, but now, need to do the top. And this is definitely not a job I’m looking forward to. I know it’s a PITA.

So I need to order the heat elements for seat, and backrest, as well as foam.. and I guess I might as well buy a new leather cover for the backrest as well...

So here are the parts I’ve been able to locate so far:

Seat heater pad -lower: 88940288
Seat heater pad -back: 88940289

Lower seat cover: 12478539
Back seat cover:

Lower foam: 12473404
Back foam:

Any help locating the part numbers (and parts!!) would be much appreciated!

check out theseatshop.com. I’ve used them twice for seat bottoms. Great quality.

R&R left rear window motor and guide, also installed those 02 wipers. The drivers side could hit the hood when folded back but you just have to install the wiper arm higher (or high enough) when it's in parked position. For me the most troublesome wiper was the passenger when I wanted to clean it with a squeegee, so this "upgrade" is nice.

One thing I noticed is the biggest difference between passenger and drivers arms is the driver has 2 spray nozzles vs the passenger and they are slightly different bend at the end. I wonder if anyone has tried using driver side arms for both for more increased wiper fluid output, or if it is worth it?

Went on a 2.5 hour trip to visit our injured dog and when I rolled up the windows the left rear would not go all the way up. My wife says "at least it isn't raining". 20 minutes into the trip back it rained nonstop :)
Luckily I could get window up about 3-4 inches from the top and with the rain guards it wasn't too bad.

So I ordered a new regulator/motor assy and while I was at it ordered new wiper arms that fold up/out like somebody mentioned in a post a while back. They were under $30 for the pair so it's worth a try so I don't have to wrestle with the squeegee when I clean the windows.
Usually you can pull up on it while the other person bumps the switch a few times and manage to get it closed.

Trucool 40k install today! I was supposed to be doing the rear brakes as well, but I’m waiting on the powder coated calipers anyway, so a couple more weeks will be fine.

I bought the factory trans cooler lines, and we followed the instructions found here, and on another site I probably shouldn’t mention here. Worked like a charm! My temps were too high for cool weather and no load on the trans. After looking in more detail at the trans information on the Tech2, finding no slips recorded, and the shift times rather reasonable, with 212k on it.. I decided I’d rather try to keep this trans going longer, so cooling it off is key.

I also installed some heat shield I bought from Summit on the lines near the trans side, since they’re really close to the headers. This is probably most of the reason I had temps too high for my liking. And of course I forgot to snap a pic of that.. it’s this stuff: https://www.summitracing.com/parts/vpe-25832

After driving around for about 15 minutes, I couldn’t get the temp over about 110° [emoji1787] guess it’s working well!! Looking forward to seeing where it goes in the heat of the summer.

Nice work! Thought you had a factory cooler, but I guess not. That TruCool should be -- to use an old phrase -- the bomb!

you might want to relocate that ambient temperature sensor, when I did mine it would say it is was 111 deg in the dic when it was really only about 85-90
