5 speed swap?

[Oldsman]

Well I'm gonna need to be changing the clutch soon so I figure I should go ahead and put me the luxurious ovrdrv gear in. Is it a simple weekend swap?

Don't think so. Will have to get the flywheel resurfaced. Normally not done on a weekend and takes a day to do.
Would be faster if a spare flywheel was resurfaced before the repair was started. Also once you start removing the trans you might see other needed repairs.

I have done a few clutches and never had the correct resurfacing done at a shop. Take some sand paper and a block and go over it till it's clean.

So yes, weekend job if you take your time IMO.
