Is this one of the 24 fret Pacers that were never released? (I have THREE of them) Notice that the "shelf" that the bridge mounting screws are attached are just recessed a little bit – not nearly as much as the rest of the recess. I don't think I've seen that on any of the 22 fret models?
ive got another lefty with the barely recessed, floyd and regular beretta like cavity cover,with 2 singles and a slanted hum,with 1 vol and 3 toggels and it came with a 22 fret american neck bound only at the headstock.
I've never seen those "in the wild", but I am sure you are right, because I just found a photo of one of mine, and it obviously isn't the same body type:
Notice the lack of room between the neck pup and neck pocket.
here is my 86/87 pacer custom, 1 volumn 3 toggles,i acquired,somebogy had filled the holes and toggle holes,this is the neck that came with it. i still havent decided on how to fix it,dont have a router and dont feel very good about tdoin it myself so its been sittin.
(in the pic u can see how close the top pup is to the neck pocket)

the bound neck with dots is the one that came with this body,the other is off my 86/87 pacer imperial
