Use same struts. If you use 86 ball joints then a 1/4" spacer is required under the ball joint fastener. If you use a 94 and up ball joint this is not req'd. The newer ball joints have a slightly shorter height.
Are you also changing the rears to Disc? If so, get the 94 and up booster, master cylinder and proportioning valve (or equivelant).
