Bought a hot rod project with a rear-end supposed to be '58 Edsel 9" Looks exactly like 57 Fords that I have used in past, but drums - which are rusted/cracked and unusable seem different. The drums are 11" in diameter and approx. 2.5 inches deep (brake shoe surface). The drums have a raised center section to allow the drum to offset toward the center of the differential. Measurement from rim to wheel mounting surface is 3". Center hole is 2.375. Wheel pattern is 5 x 4.5 " The tag on the diff. has no numbers except the ratio: 3.56 It is about 50.5 inches in width backing plate to backing plate, has smooth center section with dimples and drain on bottom. Has "small Ford" backing plate. If it is an Edsel . . . Kanter shows drums to be 200. plus - too pricey for this old man. Can you please help? 1) Is it an Edsel or Ford . . . what's the difference? 2) Do you know a source for replacement drums for Ford or Edsel? Thanks in advance.
