pattern

We recently purchased a E30+ and need to drop and rebed the keel, it's a shoal draft. Has anyone done this on this boat? I need specifically to know the pattern of the bolts, how many etc.., as it looks like we'll have to bore into the cabin sole to gain access...? So for we can see and possibly...

Does anyone know where I can find new bow cleats for a 1982 E-38 with the same hole pattern.
