[Mgs] alternator mounting

[oliver]

Hi, all.

i have a 73 b roadster with the pollution equipment mostly removed.

it had this enormous air conditioning unit that the alternator was bolted 
to.  i've removed all the a/c stuff since it never worked anyway, is almost 
as old as the car, and heavy.

i'm trying to now mount the alternator more or less as it would have come on 
a pre smog car.  i would really appreciate some pictures so i can figure 
this puzzle out.  i may have the bracket that the alternator bolts to, on 
the other side of the water pump.  but i'm pretty sure i need whatever the 
alternator swings on so it can be tightened.  none of my mg books show this. 
anyone have a spare to sell?  does it indeed move or is it solid?  if so 
what moves to get the belt on and off?

thanks!
