Question on Early Seat Rail Supports

[tom1394racing]

I am restoring a 1970 911E and have a question on the seat rail supports.

The PET lists two different versions of this part. From 1965-72, P/N 901-521-016-00 is listed as being correct. For 1973, P/N 911-521-051-01 is listed as correct. The attached photo shows two versions that I have in my stash. The pair on the RHS seems to be the same as in my '73. I am assuming then that the pair on the LHS is the correct part for the '65-'72 cars.

1. Am I correct that the LHS pair is correct for my '70E project?

2. Are the parts interchangeable? Can the early version be used in the '73 cars and vice versa?

Any help will be appreciated

I just found this photo on Pelican from a reported unmolested '68. I think this confirms my suspicion that the LHS pair above is correct for my 1970E.

I think I read somewhere that the difference is due to the difference in seat belts between the 72 and 73 models.

Comparing the two rail types, it seems like the later one could easily be modified to work in the early cars.

Can anyone confirm all of this?

Nothing stated above is correct.

Seatbelts have nothing to do with seat mounts. The 68 mounts will not work in a 69 or later car.
I will try and put together some pictures and comments to straighten out all of the misinformation you have collected.

I would appreciate it if you could straighten this out for me. Thanks in advance.

Let's start with the picture at the top of this thread.
The 2 stands on the left are from a SWB 911 or 912. Essentially 64 thru 68.
The 2 stands on the right are L to R 69 through 72 and the one on the far right is a 73.
SWB cars use the outer seat stand to lock the seat in place (notice the slots in the stand)
LWB cars use a welded piece on the center tunnel to lock the seats in place. Notice the "LWB" outer seat stand (It is almost flat with no slots).
The gray stand is an outer seat stand for a 73 car. 73s have seat locks on the inside and on the outside (the only year that did that).
Simply put, SWB cars have the seat adjuster lever on the outer side of the seat and LWB cars have the lever on the inner side of the seat.
I wish I could take a picture of the center tunnel in a LWB car showing the slotted piece that is welded to the tunnel but I don't have an example of that here at this moment. My pictures clearly show the difference between a SWB outer seat stand and a LWB outer seat stand.

Thanks so much for your explanation of the differences in the three types of seat rails. After a closer look at the PET and some of my photo archives, your explanation is crystal clear.

BTW..I have included two photos from my '73 restoration the show the center and side seat locking features you refer to.

"I wish I could take a picture of the center tunnel in a LWB car showing the slotted piece that is welded to the tunnel..."

I think this might help....a 72
