Alternator mounts not looking right...

I have absolutely no idea what year my 360 is...is there a way I can tell ?

Hoping to install the engine tomorrow but finding bolts for the flexplate has been interesting..not quite there yet.

So after reading and a lot of help from FABO members i decided that yes, I had the right brackets sold to me to mount the alternator on to the 360. They look exactly like the ones I see in a book about ebuilding a 360.

I also noticed that i didn't have a very long bolt that screws into the block plus two spacers.

Out of fun, I tossed the alternator on the car tonight just to see how it all goes together and there is no way, the long bolt will fit...the alignment is off.

Was I sold the wrong brackets or is how I have mounted, correct except for the spacer between the two ears of the alternator ?

I would not have believed that a silple issue like this could cause so much consternation.

As always, i appreciate any help.
