I found these interesting (Series I 240). Are they a standard Series I piece as opposed to the rectangular ones found on all other S30 cars?

My 70 had them.

So a Series I only part I assume.

Well well another Series I uniqueness. Could be a race part, significant weight savings there.

Of far more interest is the what appears to be a strip of door welting on the lip of the rear control arm link. Was that a Series I only item as well?

I'm having trouble imagining the purpose. Was it something you installed Gnose?

I know that one of my cars had those more shapely supports, but I checked and the ones on the red car are straight. So the ones as pictured must have been on my yellow car, which was Series 1 (10/70).

Normal for an early car.

Yep, #110 also has those shapely legs.

Those legs were on a club members Series I car but I have found the welting on the later curved rear control arm link. You all did notice that this Series I car has a curved link arm?

Yep, that was the first think that jumped out at me.

Are you sure that this a "Series 1" ? Didn't they all have the diffs mounted in the flawed location?

The photos weren't taken to show the diff which is an R190 and the car now has a 5-spd hence the curved cross member. It is a Series I (hatch, C pillar w/o air intake, metal emblem, steering wheel, oh, and the VIN number).
