Hi. I am new to the forum. I just purchased a 1971 350SL with 4.5L V8. I have a leak in the power steering and from what I understand this is common and is generally the seal(s) on the power steering pump? Question is where to buy a replacement pump or does anyone know the part numbers - OEM or aftermarket for the seals? I could really use some resources for buying some reasonably priced parts as well so I can bring the car back to its former glory!! Thanks much!
