M35 transfercase-front diff driveshaft

[Newstageowner]

Hey guys, 

just after some info. 
have been told I have to replace the front universal in the front driveshaft, 

is this a serviceable part? Or do I need to replace the whole shaft?

I am not sure on the M35 but R series and C34 stagea are not rebuildable and I assume m35 are not as well. 

Best option is to cut the uni off the old one and get a suitably sized replacement welded on (then rebalance shaft) as any 2nd hand shaft you find will be 20 years old and rooted too.
