Hi Vic
The seals are all available as modern seal equivalents. Both Bob Carriere and I have purchased seals within the last year for our respective trucks.
To start with run a search of the forum if you have not already done so, on the word “seal” you will get some useful background information.
As to the seal part numbers you will need to give us the year and size joint (5” or 6”) of the C30 and C60 it will help in identify correct seals.
Don’t know if they have outlets in the UK but I’ve had very good luck finding seals and bearings at

As to parts book I gotten excellent reproductions of the parts book from Alex Blair
