Is this the correct crossmember? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It appears to me that the current transmission crossmember on my '71 isn't the right one. The reason I think this is because the rear of the transmission seems really low, especially when you compare the angles of the transmission output and the driveshaft. So hopefully someone can confirm if this is indeed a correct auto trans. crossmember for a '67-'72.

I for sure know it's not the original crossmember since the truck used to be a three-on-the-tree truck. It also looks like the wrong transmission mount because I've never seen a round hockey puck style mount on these trucks.
