Finally getting an early A-Body

I thought so too petty, hopefully I can get the kit. All depends how the weather holds. I have alot of work just hard to do masonry when its raining. I was thinking about just buying some flat plate and welding the triangle shape I drew on the pic, boxing in the old and adding the 2 cross pieces. Do you think I need to box the whole thing in?

some one probably cut that K to install a big block,,or a deep oil pan,,just box it shut,,it wil be good as new
