Meal, yes, I know, the sad topic again. But I just don’t find any suitable contributions to my problem. So I want to replace the rear of the 04 LC4 (with “Ei” as taillight on top) against that of the 06 SMC (backlight on bottom). Now I’ve already read and found out that I need a different frame back. Does someone happen to have the part number or other suggestions for this conversion project? I already have the one-piece plastic back. + Covers, bench etc. off? Thank you for your answers.
