Re: [Amc-list] American trunnion

Tom,

Of course I'm feeling like a louse for selling you
that car.  I had no idea that you would encounter such
trouble.

You might want to check with a machine shop and see if
they have a way to drill those bolts out.  They may
have a mill with coolant to the bit.  Surely in LA
there is someone who can handle that kind of task.

I'll keep my eyes for another early sixties Rambler. 
There was a 62 American on Sacramento
craigslist(pictures show rust around the doors and
wheel wells) last week. Asking price was $500.  It's
gone now but I bet it didnt' sell.  There was a free
on in Watsonville (near my a couple of months ago).
