I truly thank everyone for their input and responses. They helped me to make a decision and it worked out great so far. I ended up giving this one a shot.

I am amazed at the construction quality as well as the fast shipping. It fits my 72 2WD T56 very nicely. They sent along a nice spacer for the trans mount but I don't think it is necessary. I slipped it into position last night very easily but don't have any pics of that yet I will try to get some today. The welds on this are very nice and I can see good penetration. I could not have made this myself even with the right equipment. The drop out middle section is a fabulous addition to a well made unit. Here are some pics of the unit before installation.
