The product was not properly packed due to its weight and shape. The pump shaft was pushed through a cardboard box. Installed in 1995 on a Chevy Suburban K1500. defect from the start. After 75 miles (1 day) of travel, this block was making more noise (crunch and rattle) than the old block. Our mechanic couldn't install it before the return deadline, so we're stuck with a defective unit. Now I have to pay to install another unit. I do not recommend this refurbished item!
