Never understood why they would have 2 different wheel offsets.. Just use one that handles both and move on.. Unless it drastically changed the wheelbase specs who would have cared..?
One of the many reasons Chevrolet needed to clean house!
In 1968, Chevrolet had 6 "basic" car models (not including trucks, vans or sub-models like Caprice, El Camino, Chevelle 300, etc...) to choose from:
1. Full size
2. Chevelle
3. Camaro
4. Nova
5. Corvette
6. Corvair
In that year, there were 16 different wheels you could get (which doesn't even include the hub cap options, which was even more)!
In 1969, again, the same 6 basic car models, but now there was over
25 different wheels in the lineup!
Now you can understand why it was such a nightmare trying to sort all this out. Not only from a salesman point of view, but all the way up to supply, assembly and budgeting!
That's the proof that rallys didn't require discs. But I'm not sure how much of the dealer lit reflected that.
Kurt, my belief is that originally, the 1968 model year was going to be like the 1967 model year (Rally wheels only available with J50/J52), but at some point they decided to offer the Rally wheels to non J50/J52 cars as well, but the documentation never got updated.
The low JZ7 option totals (8,047) reflect this. If you look at the totals for 1968:
235,147 total cars built. Of that, 20,117 came with with J50/J52 disc brakes and 7,199 came with Z28 (which required J50/J52). This leaves 207,831 cars that came with drum brakes.
I could be wrong, but I don't believe the published ZJ7 totals (8,047) include J50/J52 cars, but only drum brake cars. Do you agree?
