it won't take 2h for sure. 20 minutes job with good preparation (

Mate...joe250's post shows how to swap out the link plates....not service the linkages...the link plate swap is simple enough and takes about 20-30 minutes as long as everything goes to plan, and the needles dont drop out.
BUT there is no way you are going to get that dogbone out to service it properly, cleaned, lubed back in, in that time...impossible....even if you had Jerremy Burgess helping you.
The bolt that connects the dogbone to the frame cannot be removed until the rear exhaust header has been dropped...and it's as fiddly as ****.
You will need a 10mm 1/4" drive socket on a u/joint...with a 14" 1/4" extension. You just might get away with a 3/8" drive...but the last time I did it, I got so frustrated with it, I gave up and bought the 1/4" gear.
As well as bearings, budget for replacement exhaust gasket (about £8) it's not good practice to reuse...sods law dictates it's bound to leak when you've got it all back together.
Almost forgot.....take your time undoing the manifold nuts...if the are sized, use plenty of plus gas, or heat...don't force them...if you snap the stud, it'll be engine out time to drill retap.
I've travelled over 200 miles to s/c to get work done, and trust me, they know their ****...& they don't (not in my experience) rip peeps off..
Good luck chap...hope everything goes to plan:yes
