The 'engine hook' was first, (and last) used on the 1966 models.....so that's what you need! The '66 engine block also had a 'hook' (or loop) cast in at the rear of the block.
Hi Jess I think I have one in the garage, I'll try to dig it out Sunday and let you know if it's the right one. It came off a 1966 Riviera 425 engine. John
If John doesn't have one, let me know by pm (I don't always check this forum.) I think I might have one, but I too would need to dig through the garage to make sure.
Hello Jess Sorry for the delay, got busy and forgot to look for it. I went out in the garage this evening and found it, yes it does have the loop in it. If you haven't purchased one already I can take some photos for you to view. John
