frame switch

just wondering if i could switch my frame toa newer one i got a 88 yota wanting to change it to a 91 frame will the cab mounts be the same im only doing this because the newer frame isalmost done just liking a 4 link plus i would be useing the newer motor please help

bump no help

im not sure man, i think the bodies on the 89-94 trucks are a little wider than the 84-88 but i dont know if that reflects the frame. get a measuring tape and measure the width and length then to the bodymounts. if it is different, it may not be that hard to modify it to work for the application.
