    Jim (THEGSX),
    I have not found any as of yet, if I didn't actually see them on my GS many years ago, I wouldn't beleive they exist. Again, if you do come across some that are available, please let me know.

    Jim(The GSX), don't leave me hangin', if you did find some Terry Buick plate frames, and do not want to part with them, could you at least post a pic?

    I have a copy of a "Buick Delaer" SERVICE INFORMATION bulletin dated March 1966. Filed under group 60-9, dealer letter 66-106A.

    It shows all of the codes for engines built in 64-65-66.

    Here's the 66 codes that are listed for nailheads

    MR - 400 cu. in V-8 4 bbl, 10.25 to 1 comp.
    MS - 400 cu. in V-8 4 bbl. 11.0 to 1
    MU - 400 cu. in V-8 4 bbl. 10.25 to 1
    MT - 401 cu. in V-8 4 bbl. 10.25 to 1
    MY - 401 cu. in V-8 4 bbl. 8.75 to 1 (export)
    MW - 425 cu. in V-8 4 bbl. 10.25 to 1
    MZ - 425 cu. in V-8 2x4 bbl. 10.25 to 1

    There was some discussion on the Yahoo Nailhead group a couple of months ago that suggested that one of the "400's" - A body 401's - had the Qjet carb from the Riviera, and was rated at 356 hp ( or some other odd number close to this)

    Something else to put in your pipe and smoke.
