This is the info that I got from a guy who has done 4 or 5 conversions-Ian,
Yes it should be there. I tried the V8 install without one in 72 and the frame started to spread. So it is needed for support. The first one my Dad made while I was in service. It was basically rebar with threaded rod on the ends that he made a hook from flat stock to clamp on the outside of the framerails flange. That worked quite well. This time around, I am using the one like Falcon Enterprises sells.
