I went through this many years ago. The sleeve was purchased from moss for
approximately $35. It arrived wrapped in oil paper, in a sealed plastic bag
that said Mazda all over it, along with Mazda's part numbers. I took the
block to my machine shop for the installation that I had been told
previously would run $32. What they neglected to tell me was the $32 charge
included the same Mazda sleeve! I still don't know who felt gouged the
most... the block or me. Or maybe the machine shop works for free and sells
sleeves at reduced prices.
