Hi over the winter I picked up a 1969 GS , It originally came with a 400 motor from the factory ..unfortunately it has a 1970 GS 350 motor in it now ..the frame mounts have been moved from its original holes ..can i use the same frame mounts just relocate them back to the original location in order to install the 455 motor ? the transmission is a turbo 400 not sure if its the original..is there any other modes im forgetting..?
