that pinion yoke is very easy to swap....really very easy...if it was setup right the pinion flange should just slide off with a slight tap if needed...
i had mine rebuilt but flange got damaged ,,causing viberation...
i had used all hand tools and just snugged it with holding flange with hand..just dont over tighten
i have a dirt driveway and homemade drive on ramps..
flange/ujoint/balance will be 1/2 the price of a new custom...
what will actually make it easier for me too is that this rear was built with a solid pinion spacer, no crush sleeve, so i can't mess up the preload even if i tried to lol
