I just did this for our sunliner, and did it through rockauto. I also had them do the power steering control valve at the same time. Order/pay through Rock Auto, and it ships directly to Lares. Lares did great work, and it was about a week turnaround. Was the lowest price I could find too.
The Lares website also shows that they work with one of the large parts chains (maybe AutoZone), but i couldnt find the rebuild listed on their website; maybe someone in the store would know if they do it, but that would probably save the hassle of shipping it.
