Kevko oil pans?
Let me just mention the fact that on my '65 Valiant Bracket racer I used the larger lower control arm stops (see first foto) to help protect the rear-sump ten quart oil pan (with steering link tunnel) from getting smashed.
If you look carefully (in the second foto), you can see how I painted the bottom one inch or so of the oil pan bright white so I could easily spot/monitor any damage to the bottom of the pan.
I will probably use the same procedure when I install the Kevko oil pan in my '72 BBody.
P.S. I also used the large control arm stop on my bracket racer's pinion snubber.
