Front Strut Tower Reinforcement Plates

[JDP530]

Does anyone know if the E46 or E36 front upper strut tower plates will work on the E31? I would like to reinforce the underside of the front strut towers before I install a set of coilovers. Thanks,

E36 part #31312489795

E46 part #51717036781

I may have found the answer to my question because the camber plates they sent to me fit the E36. I probably dont need the reinforcment plates after comparing a photo of OEM reinforcement plates with the additional 'pointer' plates include with the GC camber plates. The pointer plate is stainless, apprx 2.50 mm thick, and a 133 mm diameter.
