Most of the 123 300 TD and TDT had a manual sliding roof.. If your power sliding roof has gone bad using one of those is a common thing as every thing fits except you have to remove the cable from the roof area.. so it will not hit any thing.. I am not real sure as I have not done it but one fellow told me he only had to use the parts from the manual and kept the metal outer part so he did not have to repaint it..
