I know that that the 603 found in 124 wagons and in w140 sd models had a dual power steering/sls pump at least within the US. I've seen a few examples of a non-turbo 603 having the older style (read: s123/617) pump bolted to the head. Does anyone know if the head is any different?

Is there a way to mount the sls pump to a 603 head instead of using the dual pump?

The main reason I'm asking is I'm trying to plan out the engine bay of a 603 in a s123, and keeping the SLS system operational. The SLS reservior on the s123 (except for '85) appears to be only on the passenger's side while the 603 in the 87 s124 configuration has the dual pump and SLS reservoir on the driver's side. I'd like to know if I can keep things on the passenger's side (who knows where) or if I'm forced to route the high pressure line/low pressure return across the engine bay.

Examples

(yes I know this is a 602)
