I am using there adapter and found that with the truck accessories on the front of the motor i could not get the engine/trans perfectly straight
If i bolted the trans mount to the original holes in the cross member and split the clearance at the front so a/c and power steering resevoir fit between the frame rails the whole thing sat a little crooked. I decided to re drill the cross member by moving the holes to the passenger side 3/4" and forward 1/2". That left me with a motor/trans that was parallel with the frame but off set to the passenger side slighly and improved firewall clearance so it did not need to be hammered in to clear the valve cover. If you look through my posts you should be able to see the pics showing the tie rod and oil pan clearance.
