I have an '83 12A engine with the tapped holes as you say.  But the
'86+ 13Bs don't have those holes.  One option is to use the 12A
front cover on the 13B, if it will work.  The other option which
I'm leaning towards is drilling holes in these flat plate protrutions
on the 13B front cover.  Does anyone know for certain if the 12A
front covers will work on the 13B?

You took the question right out of my mouth. I"m not building a LongEZ but I
have the same question. I have a 74-79 13B and an 87 13B. I'm planning on
using the 87 in the plane. The 74-79 13B front cover looks like it has the
same bolt pattern as the 87 13b. I want to use the 74-79 front cover because
it has the same flat plate that you guys are describing with 4 bolts as the
12A (I think) which gives me a place to tie it to the mount. I'll try
swapping it out this weekend. As far as a 12A front cover, I'm not sure.
