I read somewhere that the 74 REPU's are the only ones with 4.6 rears, but I came across the Racing Beat tech manual and it lists 74 and 75 with 4.6 rear ends.
Can anyone confirm this? With the rear apart how can you tell?
Many 74's did not sell in 74 and were in fact resold as 75 models. So I can see that happening.
To get the rear end ratio, divide the # of teeth on the ring gear by the # of teeth on the pinion gear.
