balancing drive shaft

Thanks all,
Will be getting my TR4 prop shaft balanced.
My car will be apart for some time yet (year or two) but balancing seems the 
right thing to do especially since I don't know the history on this shaft.
ps; $45 is for installing joints (I removed the old ones and cleaned 
everything) and balancing, and maybe a shot of paint. I am supplying one Spicer 
u-joint and a GNK u-joint (I think they are same company these days?).
regards,
Carl
