1990 Sierra Manual to Automatic conversion

Hey guys. I have a 1990 GMC Sierra. V-6 with 5 speed manual tranny. I am wanting to convert it to auto but am not sure what is involved and information is hard to find. Can someone please advise me?

Obviously the I would need the auto tranny, column shifter, radiator with cooling lines and get rid of clutch. What are some other things that would have to be done? Any assistance /info would be greatly appreciated.

Please forget about this stupid idea of mine. Really, was just curious but judging from the lack of response to the post this is not a very good idea.

Thanks

Correct.
