Does This Debunk the "Coolant Can Flow Through the Radiator Too Fast" Idea???

Well your right my mind is made up. I know what is working for me. It's ok to have different thoughts on this, if we didn't we wouldn't have these forums. Now lets get off that for a second. I bought an adjustable pinion snubber for my 66 Barracuda. Heres my question should I put a steel plate up to reinforce the body where the snubber will be hitting and should I put the snubber right up against it or down a little.
