I need a new speedometer for my 1989 300ce. The Mercedes dealer says that the 1988 will not fit nor will a 1990-up. Is this true? My car is a Canadian model and the part number on the front of the speedo is 124 542 58 67. I called a local salvage yard and they said that the only one different is that one from a 4 MATIC, because it has what they call a "TV" meaning the small screen. I'm asking, because it will be cheaper for me to buy a used cluster than buying a new speedo from the dealer who wants $746.35 Canadian funds. I just want to know which years will fit.

Thank You in Advance
