Help ID this set of pedals if they are from Slant, 318 or HD style like 340 and BB darts

I believe those are standard duty pedals, from how the spring mounts on the side. Also, the spring itself is not as beefy as the HD unit.

The HD assembly has a caged spring that mounts on a pin at the front. You can see in the pic below where the spring goes, but the spring isn't in there. You can also see the HD spring sitting on the table next to the assembly.

You can also tell by the over sized bushings in the pivot, but you'd need to disassemble it to find out.

Ultimately, you will probably not even need the spring anyway. The new diaphragm clutches require you to remove the over center spring.

Thanks John for the pics!!!
Just what I wanted to see the difference.
Being standard duty do you see any issue using this with an a833 OEM performance clutch and a 360/408 stoker. I’m still up in air about that or 318/390 I have both kits but if I do this car I will prob do the 408. I was thinking gen3 and 5 speed but I’m more of a purist and OEM guy and also I’ve never done a 5 speed and hate to cut so much out of the trans tunnel. The slant isnt cutting it for me especially with the column shifter. I need that third pedal like a junior needs another shot!
