Truck 4 speed trans
 

The 460 I put in my 66 has issues so I was offered a good 352 and since I still have the original FE mounts and clutch parts I am going to put it in,I was wanting to put my toploader 4 speed in but my bellhousing is too deep as the truck 4 speeds have a longer input shaft so I am thinking on finding another since the original 4 speed was worn out and got scrapped. Now what I need to know is do all the years of truck 4 speeds have a longer input shaft and what years have a switch for back up lights since I added 67 to 72 back up light s to my 66 and would still like them to work.
