On time shipping, perfect fit, good quality new part. Not that rebuilt crap from parts store. Bought steering box as well and just as happy with it too.

Shipping was on time, part was factory correct. Installed in a short period of time. Price was not bad. Would suggest replacing or upgrading the power steering lines and boost lines when installing the Hydroboost.
