You will have differing holes in the door for those two mirror versions.......some will need to be welded up + paint, some new to be drilled in. The old holes will not be covered by the early mirror

If you went for the non electric manual adj mirrors they bolt right up to existing holes......no messing about and weigh next to nothing compared to electric.

Yep, I tried looking for any set and these early mirrors happened to come up for me before the later style manual mirrors did. I would be curious what the weight difference is per mirror of the later style manual vs early style manual. I think there is a guy making reproductions of this later style (as well as other body parts) though I did not find out about this until after getting this pair.

Thankfully the service manual shows the correct measurements to place the old style mirror. Now to learn how to weld...

This is the guy making reproduction parts (including the mirrors) in the EU somewhere. He wants $300/set shipped.

Welp, I can't shift into 2nd gear now for some reason, like it won't let me push the shifter all the way forward as I need to.. This just happened on a drive with my daughter -- quite unsettling coming out of a corner. I've got all the other gears. Just 2nd won't engage, even with the car stationary. I pulled up the boot around the shifter and nothing's blocking it. Until the middle of the drive today it was going fine...

It's a rebuilt trans, so shouldn't be internal. My first concern is that the u-joint coupler to the gear selector input shaft has shifted or come loose.

Dan, I was thinking the same thing. I remembered you telling me that (and being super grateful) when I got the thing, thinking one less thing to worry about! Still no grinding or anything strange, just no 2nd gear to be had..

So to do this, I have to drop the transmission yeah?

Wow it's been MONTHS... I really want to drive this car

Finally got to the transmission this weekend. Linkage was all good, the bolt on the u-joint coupler was just fine as was the coupler itself. After getting the transmission out of the way, I could see the cup-end on the fixed linkage point was also in good shape.

So that was a pain in the butt, but not the worst job I've ever done. Those top two bolts, especially the driver's side with the u-joint in the way, were the worst part of it. If I had a lift it would have been a bit simpler. Having a transmission floor jack with a strap helped a TON.

While it's out I've got new boots and bolts for the axles. Anything else I should refurb while I'm in there? Part of me is saying "just drop the torsion tube and refresh those bushes".. with the gearbox out that's probably the time to do it, huh.. while I'm in there maybe reindex the bars and drop an inch or so. I am also planning on this being the race car, so I'm tempted by stiffer bars, and also to zip off the rear center tunnel for easier linkage and transmission work next time. I've got some thinking, and research, to do.

And now with the transmission out, I think I'm just going to drain it and crack the case and see what I can see. It's not shifting into 2nd and so I'm expecting to see some obstruction or something misaligned inside the box. If that is not the case, I'll probably have a professional look at it; this is the first time I've ever done anything with a gearbox, and of all the automotive things it's the most foreign to me. I have a manual and there are a couple good posts on the board, so we will see where I end up once the front of the case is off.

Its likely just the same issue as in all G31's... dreaded synchro


http://m-elliott.us/Porsche/G31Rebuild.htm

I did it once a loooong time ago before digital cameras and have yet to find any pictures

Edit: But...it was rebuilt so lets hope its something else. When I rebuilt mine I still had issues shifting afterward which was depressing. I ended up being really good at double clutching
