if you do use one of these, I would recommend having a machine shop check the mounting surfaces for straightness. I installed a used Lakewood sc. shield and could not get the alignment within spec after many attempts. Turns out the mounting surface had to be machined .030". Once that was done, it fell into place. Don't assume it's still straight after all these years.An install tip, buy the offset dowels that have the set screw center and flats on the outside as opposed to the cheaper ones that just have a screwdriver slot and no locking mechanism.

either will work as long as the register hole matches the trans register size. personally I would get the corvette aluminum one just for the huge weight savings, and those are usually big bucks so if you get a deal its a win win. neither should have the issue mentioned in the above post.
