    630679 is rated 4.7 out of 5 by 16.
    Rated 4 out of 5 by from Excellent finish & has Delco stamping Installed this booster two weeks ago and it works great. I didn’t use the new master cyl because the piston size was smaller and had a deeper recessed area than my original. The kit did include a longer pushrod to facilitate using the new cylinder. The booster was exact replacement of my original. This kit was cheaper than a stand alone Delco booster from any competitor.
