top is left, bottom is right..... photo rotated for some reason..... and is large....
No kidding !!! ... it's gigantic ... just like those *****
The straight one, as you point out, is for the 78 - 79. The bent one suits 80 (or maybe later) and up, and is the one I have on my 82. The bent one is used where the front shaft is mounted using a guide bracket on the TT, and the straight one is for where the front shaft guide bracket is mounted on the transmission tunnel, on the early cars.
the bent one is the older model , I think. Ill have to pull out my spares and see...I thought i got one as an assembly from Mark and didnt need this part of it, only the ball cup.
Check PET and you will see that there is no differentiation pictorially (of the shaft), but it does show that the bracket on the early cars is connected to the tunnel, and as we all know, is on the TT on all the later ones. Where the bracket is on the tunnel, the straight shaft is used, as that bracket holds the shaft up higher than the TT. The later ones, which are mounted on the TT, need the bent shaft to bring them up to the same level.
Here is a pic of my 82 complete shifter assembly. In the pic you can see it needs the bend to get it up to the correct height ... where it's mounted higher, on the tunnel on early cars, it's already high enough, and doesn't need the upward bend.
If you need any more convincing check your own car ... but not the spare, that you got the ball cup from, which might be early or late.

Reason: grammar
so if the early EARLY cars have the straight one, body mount linkage, then after say, 80-, the links have a bend and are all the same, so the shifters could really be interchanged?
thats what I'm trying to figure out, did the linkage change or just the leverage needed for the syncro type?
928.424.009.001 78-79
928.424.009.008 80-84
928.424.009.010 85-up
What is clear is that 001 is the early straight, and 008 and 010 are bent shafts. The only way to be sure of the difference between the 008 and 010 will be to measure the differences between the two (if any). I can post all the measurements if you like, and hopefully someone else can measure their post 85 one.
I have a spare of the 82 so can measure that in detail, but don't have my GTS one out of the car. Two variables that I can think are possible are the rise height, and the overall length, to accommodate a slightly different gearlever position or TT length ??
The shifters obviously give two variations of throw, relative to stock ...
1. Shorter shifter shaft gives shorter overall length of throw at the gear ****.
2. Greater spacing of the bushes gives shorter overall length of throw at the gear ****.
After stumbling upon this thread it appears that my car has been possibly updated with a later “bent” rod linkage. The car is an early ‘78 (#338 USA) with the linkage guide bushing that attaches to the body of the car (as opposed to the later versions in which it attached to the torque tube). What’s adding to my confusion is that the WSM addresses these early cars with the body-mounted bushing, but the picture they use shows a bent rod. It’s in section 34-8 of the WSM.

For anyone interested, there are supposedly only twelve of the early -01 straight shafts available from Porsche. They are all in Germany and I recently bought one of them.
