Mk2 with 4lug 15" wheels.

My question is, will a conversion kit for 87-93 mustang from say LMR.com work or another 5.0 mustang parts company? Or do I need to buy factory five products in order to convert? Just would like to upgrade my 15+ yr old car wheels, brakes, suspension to modern technology. I believe all my components are from a 5.0 donor car so my theory is that it should all be dorect replacements..
