Got the holes drilled......just to take my time....and have them installed with a small 1/4" gap along about a 6" portion on the rear. Both of them are this way....and its just kinda how they fit.....

So....I will probably have to beta-link the top edge....and make it permanent. Its only a bumper...whicj in my book is a replaceable wear surface....kind of like a bushing. Temp pics below. Only positive comments welcome...lol.
