I would like to drop a 1970 olds 350 I have just sitting in my garage in my 87 Monte ls I've done some research and I'm confused on which motor mount combination I would need ? Are the frame mounts for the same year as say cutlass with a olds 305 a part I would have to hunt down or does someone sell these? Could someone help me with some images maybe , or any help I would greatly appreciate! Thanks in advance.
