Wallace has a good resource for torque specs. Check link.
5 X 4.75
Looks like it will fit. 2006 pattern is actually a 5 x 120mm. See discussion in link
No, Mustang wheels will not fit a GTO the bolt pattern is 5 x 120.65 mm (4.75 inches) on a GTO; it's 5 x 114.3 (4.5 inches) on '94-up Mustangs. Prior to that, the Mustang had a 4-bolt setup. Lastly, the wheel offset is different on each car (offset might be cured with spacers, but it's a mute point with the difference in bolt spacing).
The Rear Axel for a 1969 Pontiac GTO is 60"
Starting at the center of the head under the valve cover (bolt #1) the torque sequence is: 7 3 1 5 9 8 4 2 6 10 Make sure all bolt threads and threads in the block are clean and lubricated lightly with oil. Pontiac do not need thread sealent since the bolts do not break into the water jackets. Start in the middle of the head and move outward.Torque in three steps first all bolts to 30lbft, then all to 60lbft, finally all bolts to 95lbft. after inital run in recheck the final (95lbft) torque after the engine has cooled.
Yes. It will bolt right in with 1968 motor mounts.
5x4.75 also know as GM small bolt pattern, same as firebird, camaro, vetter, GTO, chevelle, Monte Carlo, cutlass, s-10, corvette
Yes.
5x120This is the metric equivalent to 5 on 4 3/4. Meaning most wheels for GM cars will bolt right up. This does not include pickups..(except the S-10) or the older large bodied cars that used 5x5.
Right hand thread
facing the head of the plug bolt, you should be turning counter-clockwise. Common dude, remember "righty tighty, lefty loosey"? Oldschool.
you have to remove the front fascia along with removing the three bolts that are easy to see.
