Steve B Posted February 19, 2005 Share Posted February 19, 2005 MZ is correct for the 66 425 2x4. In addition to the codes Scott listed above, there was also the MS 400 (401) 11 to 1 compression, the MU 400 (401) 10.25 to 1 compression, and the MY 401 8.75 to 1 compression export. There was no MX in 66, but there was a LX (425 2x4) in 65 and a KX (425 2x4) in 64. Link to comment Share on other sites More sharing options...
