Summary:
Part page mentions the need to adjust the pushrod. Total adjustment is only about 1/4 inch. However, the piston in my 67 C10 master cylinder is recessed 1 3/8 inches. Of course, that won't work. A call to the tech help line revealed that I needed an additional "slug extension" to make up the difference. It would have been nice to have a caveat warning on the part page that some installations would need that extra part. Thanks to Kevin for hooking me up with that slug.
Cons:
Needed a Plunger Slug # 91031445.1.
Pros:
Excellent part
Yes, I recommend this product.
Works well for being a reasonably small diameter
