Everett, maybe someone who knows for sure will reply, but here's what I know 
(or think)-the big bolts on the end of the heads are 3/8 thread (9/16 head) 
on earlies and 65s.  On later lates they are smaller-5/16 threads (1/2 
head).  It's good you have the 3/8 head ones-the normal size of the head is 
7/16 (they are 1/4 threads) and a normal size head won't fit for the bottom 
shrouds and some other places.  The only possible substitute is an allen 
head bolt.  Not sure about the self-tappers but if nobody else can tell you, 
I'll pull one out of my 64.
Hope this helps,
