    I have a 70 K5 with sm456 & np205. I am pullin out that combo (and its for sale with everything including a new clutch with 8 miles) and have a 88 K5 donor truck. I want to put in the TBI motor and 700r4 w/ np208. I have a bunch of questions...I will start one post here and a post for each of the other questions.
    <font color="red"> cross member: </font> can I use the one from the 88? Will I need to modify it to fit? The frame rails both measure about 34" where the cross member sits?
    Also, I want a body lift? and suggestions? 1 or 3 inches? From who? what brand?
