Hmmm...
I've got a set that looks like those! Bought them on ebay, advertised as A body pedals. I bought them 'cause I heard they would fit, and the restored version I got cost
a lot less than most of the "in need of restoration" e-body sets (how on earth did you get a set for 40 bucks?! most I see go for 200+!). The pedals measure about 11 3/4" from center of pivot to center of pedal, and the funny looking brake pedal has the number 3182 stamped into it. Not sure if this will help, because they may not actually be a-body pedals (gotta love eBay!), but I thought I'd throw it out there...
