I AM CURRENTLY INSTALLING A 302 INTO MY 1977 cRUISER AND I HAD TO SWITCH mounts left mount goes onto right, and then bolt your engine to it using long bolt, doing the left side is a little tougher, I had to remove mount bolts from engine, install frame mount to engine mount, and then line the engine up making sure the transmission tail did not slip one side to the other, I was able to get the long bolt in with cajoling and cussing, and I managed to get one(1) frame mount bolt in, next you either need to hope you have a second left side motor mount, or re-drill 5/16 graduating to 3/8 hole to match the engines comfort fit (lined up no stress on mount) the factory frame bolts are 3/8x3/4" 1/2" head with 9/16 bolt, I have run across several problems the so-called PROS here have decided it was not worthy mentioning, a Mustang sway bar is needed, but to mount it you must once again do modifications by making a plate for both sides, to mount onto the pinto underframe, then bolt the sway bar to that plate If I had my choices, and knew this I would not have proceeded, lucky for me I had a Mustang II to cannibalize, but it had 2 right side mounts on it (screwed again) So I am using a Borg Warner RAD 4 Speed, had to buy a new clutch cable (for a Merkur) and still trying to figure the radiator as I type this, and U will also need (unless your tranny fits) the driveshaft or Yoke OH and before I forget, I had a brand new pair of Hooker Headers designed in the late 70's for Pinto swap... must be 79 or 80, because they don't fit on a 77, so I used the factory manifolds from the Mustang II PERFECT !!!! a lot more work to do b4 I even start it. BUT I AM STILL TICKLED
