Does anyone have the frame specifications for a 1986 Chev Silverado Short box. I am putting a low mileage v6 in the truck from a 1987 GMC Wrangler. The motor will not fit between the frame rails. The frame towers are in the right spots and when the drivers side mount in bolted in the passengers side motor mount does not fit in the proper place. The bolt that the slots in the motor bracket fit over are about an inch out. I am looking for the specs that will allow me to measure the frame from side to side and the distance between the frame rails where the lower control arms bolt to. I have a funny feeling that the frame has a kink in it. Thanks to all those that may be able to help.
