Engine mount nut sizes

[Scott06]

2003 vintage since I turned a 4.3 into a 5.0 I technically dont have a merc serial. Original 4.3 serial was OM694685, that is what the side engine mounts are from.

I am going to do an alignment - what size are the adjustment nuts on the side engine mounts? I thought they were 1 & 1/16" or 1 & 1/8" - I wanted to buy crows foot sockets to get at this easier..

My 5.0L from 1985 was a 1-1/16" if that helps. The newer'ish 383 MAGs use the same size.
