My 1977 clipper wore out power steering belts every 500-1000 miles. The fix was to add the extra idler and belt for the water pump. I believe this was added on the 1978/9 models. Contact your dodge dealer for the parts.
This is an addition to the P/S belts. Issue #29 had the Dodge part#s required. The second water pump belt/idler came with the 1979 Dodges. Here is a list of qty/part #/desc
