wheel bolt pattern 67 coronet wagon

-
As a rule of thumb, all A-Bodies from 1960 up to and including 1972 were small bolt pattern front and rear.
(4'' bolt circle with 7/16'' wheel studs X5)
And starting for the 73 model year, all V8 and slant 6 with power brakes got the big bolt pattern front and rear.
(4 1/2'' bolt circle with 1/2'' wheel studs X5)
And, all A-Bodies built after December 31, 1976 were all big bolt pattern regardless of engine.

Your '67 Coronet wagon is a B-Body, and all B-Bodies had big bolt pattern. (5 on 4 1/2'')
That is of course unless someone changed it to small bolt pattern, which is highly unlikely.
 
thanks...i see there is no brake booster for power brakes.was this factory drums in the front?i dont think anyone has messed with anything from stock.i travelling a bit today to look at this car and hopefully buy.should it have an 8 3/4 rear?anything else should i pay special attention to?
 
Absence of a brake booster only means that there is no power assist, not any indicator of the type of brakes on the car. My Barracuda has standard disc brakes, the "power" was an option.

So, you could get an early 1976 Duster slant six with a small bolt circle? Wow!!

December 31, ‘75.
On Jan 1 ‘76 the federal mandate for front disks kicked in, and they were all 5x4.5”.

Also, power brakes wasn’t the determining factor. All V8 A-bodies starting in model year ‘73 had disks regardless of whether they were power brakes or not, and starting in '73 all the disks were BBP. /6 cars with no options were standard drums, so, SBP. But if they got an option that triggered disk brakes, they were then BBP.

My '74 Duster was a /6 with factory manual disks, BBP. It was one of the only options it had, but it came with them as a factory option.

Yes. But it had to be /6 car with standard drum brakes. If you got your /6 with a sure grip, or 3.55 gears, that triggered front disk brakes. Same for the optional towing package, you could get a /6 with a towing package, but it would have disk brakes!
