NEED HELP ASAP 1989-1991 Suburban Power Mirrors On 1987 GMC Truck

[GMC85HighSierra]

Hi all, I was seeing if anyone has put the 89 91 Suburban power mirrors on their truck, and how to do it. I want a set for my 1987 GMC truck, mainly because I'm too lazy to keep going out to adjust them LOL. I found a set of burb power mirrors I can get for $25, but trying to see how to install them in place of the standard chrome mirrors. Also what all I'll need to grab off of it to do the conversion. Need to know ASAP before someone else grabs them or it gets crushed. Thanks
