carb to spfi

hey all, I have an 86 gl 3dr cp with carb and and 89 somewhat wrecked 89 3dr cp. I would am trying to get the 86 on the road and would like to put the fuel inj. on the 86. what parts and or modifications need to be done. the 86 has 97,000 and the 89 has 190,000 on the odometer. the 89 runs beautifully when it starts, just have to push it and dump the clutch, electrical gremlins, aka squirrels.

thanks for any and all input anybody has.
