I think I found one at Napa and at least one other local supplier, but the price was not anything all that great, and I decided that I would get a better and more thorough job for the price doung it myself. More control over the components used and I knew I would replace anything that was good enough but not great. I don't want to have to do this again for another 250,000 moles.
If you want, I will remember check my records and see who exactly we called, they were not new crate motors, but remamufacured ones, they were hard to find and a bit pricey, one was only a 90 day warranty, the other was a year.
