fitting PAS to 87 ex mod 90

Hi
I am new to the forum. I have previously owned a 90, a couple of old range's and a disco but i have decided to go back to a bog standard 90. I need advice re fitting PAS to my "new" 90 an 87 ex mod 90. Can someone tell me exactly what parts i will need to source for this project?
Cheers

Does it use a recon (green paint) 2.5 NA Diesel engine ?

Not sure what you'd need for them, but we'd need more info on the current state of your engine
