MGB Main Bearings

[pokrefke1@comcast.net]

I am (literally) in the process of inspecting/replacing the main bearings in my 
1970 MGB while the engine sits in the car.  I am having difficulty removing the 
front and rear main bearing caps.  Is it possible to remove these caps while 
the engine is in the car, or are there hidden bolts I can't see?  Any words of 
wisdom to share?  The last time I did this I let Dad do most of the work while 
I drank the beer.

Thank you in advance,
