Hello Terence,
I might be able to help you. I've got a built up and painted Academy M1A2 SEP kit, it should have all the parts you're looking for. I decided not to go any further on the diorama plans I had for it. I also have Verlinden's resin IDF M60 Blazer Armor. Both are listed inMy Trade/Sale List

I'll send you an email as well and can get you some photos of the SEP if you want.
