Early 911 seat rail dimensions needed

[kecho]

Can anyone with an early SWB 911 (1964-1968) tell me what the measurement of the seat rails (across~center-to-center) is. I have some early Recaro's and the rails are spread apart 16 1/8 inch on center. I have a stock set of seats taken out of a later (1969) car that are much wider. If you're lucky enough to have both SWB and LWB cars, I'd appreciate knowing both measurements. Thanks!

You want to make some adapter plates for later seats in an early car?

Try this:

Harry-I think those plates are for adapting 74 and later seats to 73 and earlier.

I don't know that there is a difference between SWB and LWB seat mounting. I checked Corbeau's website and they sell one bracket for 65-73 and one for 74-89.

Todd,

Todd you are correct about the purpose of the plates.

I am not sure but I have always thought that the early seats (65-73) were on an 18.? spacing and the later seats (74+) were on a 16" spacing.

There are differences between the area's of mounting on the factory sport seats, and the standard seats in the 65 to 73 cars.

I just measured a 16" center to center on my SWB sport seat rails and 15.5" on my LWB sport seat rails. Stock seats are 18" rail to rail.

Note that the sport seats bolt through the brackets which are placed to the outside of the rails, and the standard seats bolt "though" the rails...therefore the wider width on a standard seat.

Any other questions on sport seats, I'd be happy to help...I've got quite a few sets laying around right now, both SWB and LWB.

Not sure I was clear....stock seats are interchangeable from 65 to 73...the approx width between the bolt holes is 18".

The sport seats have bottom "bases/brackets" which attach to the seats....it's these bases that bolt to the floors, THEN you bolt the seats to the bases.

Note that the bases are very different between SWB and LWB sport seats. The SWB sport seats have sliders built into the seats, and the LWB seats have the slider rails built into the bottom brackets.

Sorry I don't have pics handy, I'm on a dial up line today. Do a search on SWBSAM over on the Early S Registry, and you should be able to find the pics that Sam has posted over the years, his are pretty clear.

Eric

Harry-Yep, those dimensions are what I've measured as well.
