The code on the housing is best seen by looking straight up at the bottom or the housing about 2 inches rearward of the strut rod mounting bracket. Need to remove the heatshield, I believe. My 79 is OJ, 3.70 but looks like UJ(bad stamping?, 79 uses O also)More toward the drivers side of the housing. If anyone knows, could 1980 be UJ? My 79 is very, very late 79. If anyone spots the code, let us know. Mike

If I am turning 3500 RPM @ 75 MPH and you're turning 3500 @ 70 MPH, we both need a 700R4 overdrive. Mine is going in this weekend!!
