[C320-list] Jabsco Head replacement

[Scott Thompson]

I managed to crack the pump assembly while overhauling it today.  WM is 
running a sale on the latest version of the Jabsco Compact Manual head, 
which appears to be a drop-in replacement for the one that came on 
Surprise, and which costs only a few dollars more than the pump 
assembly, which isn't in stock anyhow.  So I bought one.  Wish I had 
done that first!

It appears to be a simple case of unbolt the old one and bolt on the new 
one.  Dimensions are identical.

However, I am reluctant to unbolt the old one without a better 
understand of how it is attached.  I don't see any way to get at the 
back of the fiberglass unit to which it is bolted.

Can anyone who has removed their original head tell me how they are 
attached?  I'm hoping there are attached nuts or threaded plates, or 
maybe it's just mounted via lag bolts into a wooden framework.  If there 
are loose nuts on the backing then I have a problem.
