If this is the case You can mount them either way. But I’d put them on the front then you can source stock 73 A body with disc brakes parts, ie: hoses and calipers, and the brake hose routing is the way it should be..
if you choose to rear mount them buy calipers listed for cars like an 85 dodge diplomat, or Chrysler New Yorker. Then you can install them properly with the feed on the bottom and the bleeder in the top. And also of course the 69’ camaro with disc brake hose…
don’t forget to put a 73 and up A body disc brake proportioning valve on the car too.
people seem to sell them for around 85 bucks. I think I saw inline tube selling them on eBay for 65 dollars but I’m not sure about the shipping charges. Maybe inline tube also just sells direct. Doctor Diff is another source
