Thanks again for all of the info...I ended up getting the rebuilt Denso starter from Big 2 in Chandler....they came close to matching Camelback and it was a lot shorter drive for me.
I decided on a complete unit instead of replacing the contacts simply account I am now 77 and I would rather just R&R the unit and not worry about doing something wrong and then having to remove the unit and try again.
It took my neighbor and I about 1 1/2 hours total time - not bad seeing as how it is a very tight fit. The youtube videos helped and as others said, the new starter does turn over quicker. It seemed to be the same physical size which was something I was concerned about, but it fit right in.
This was only the 3rd major item I've had to replace since I bought the truck new in May 1998. A new radiator (and with a separate transmission oil cooler), lower ball joints and now the starter. Not bad for a car that is almost 30 years old, albeit with only 113317 miles on it.
