If memory serves me, a 1928 Chrysler 6 should be a model 62. Model 58 is year 1926. Also, a bit of information for anyone having clutch problems. I have a 1927 model 60 on which the clutch plate was actually broken in half. I found that by counter boring and counter sinking the flywheel bolts, that a 1940 Ford clutch plate fits very well. Same spline, same diameter. The Chrysler might be a bit ashamed to have a Ford part, but it works!
