1975 Porsche Cylinder Head Leak
 

Hey guys, not sure if this is the right area to post in, but I have an issue with a Porsche 911 ('75) that I am interested in buying.

The cylinder head is leaking oil and two axle shafts look shot.

Anyone know the costs of these parts or where to get them?
And time expected for labour?

Any help is appreciated.

Thanks
Brad
