'71 T/A Auto 58.2% Manual 41.8%
'72 T/A Auto 64.4% Manual 35.6%
'73 455 T/A Auto 68.8% Manual 31.2%
'73 SD T/A Auto 71.4% Manual 28.6%
Thanks RicksGTO,

I did not know the RA was mandatory with the HO. The PHS shows it, so I guess it was a package deal then. I am just starting to learn these 72 monsters

Ok, to add (or subtract) to the stick percentage, what would be a good guess at this car with the M22?
Oh, these were 12 bolt like the 72 GTO's as well right?
