[Healeys] Clutch question

[CAWS52803 at aol.com]

I have no clutch!  The pedal goes to the metal!
If I pump it 5 - 10 times, I might be able to shift it into gear.  I'm not 
losing any fluid.  Oh yes, it's a BN4 with separate clutch & brake fluid 
cylinders.
I am going to remove, hone and replace the inner seals.
My question - Is this something I should undertake myself?  I do have the 
parts list and owners manuals for a guide.
Any suggestions or help?
