Andy. Would you consider that removable rad core brace strong as a bolted in part as apposed to the factory welded in one piece?
I'm sure the bolt in design gives up some strength but I can pull the engine and trans with the shifter linkage still attached to the trans in just a few minutes. With the stock core support in place it gets very, very difficult to wiggle the whole assembly out of there, especially with a deep oil pan. I can gain the strength back in other places so that doesn't worry me. I prefer to be able to slide the engine in and out quickly since I'm constantly working on this car.
