I used them for installing my tranny, they seem to know what there doing. The price tag was a little on the heavy side. I know I asked them to quote me a price for installing a gauge that I would provide, and he told me 400.00 I asked why so high and he responded that since he wasn't supplying the gauge that he couldn't make any money, so I did it myself. For straight diesel engine work there's J & S diesel on Industrial.(non high performance)
