1989 Camaro RS Convertible 305 TBI with A/C

I'm doing a engine swap and broke the power steering pump bracket, so I got a new one in as well as a new pump and pulley, hoses. but I can't seem to find the bolts listed anywhere or their sizes. The last yahoo under my hood put the pulley on so bad that it's not coming off without a torch or a cut off wheel. All I need is those stinking grade 8 torx head, button heads that hold the pump to the bracket.

Anyone have a parts book with what I"m after listed?

Or know what size, pitch, thread, length I need and or a source?

I have not had any luck thus far googling the internet or this site.

thanks in advance.
