I have a pair of very good front seat bench springs that are in my 123.
rock solid and no lean at all. Way too hard for me, like sitting on a park bench. SPRINGS ONLY! I am going to put my w126 seats in my 123.
$50 each + shipping

Do you still have the seat springs for sale? Would these fit in a 1985 300 turbo diesel?

No, I don't have them anymore, But, yes they will fit in an 85.
Any of the springs from a w123,126,116 will fit into your 85 300D
