haha, no i forgot who gave me that. but ya, i would reset the pinion angle at the same time.
this is from that link talking about it, quote: While I was at it, Rob convinced me to angle this new perch so that the pinion pointed towards the xfer case output. This provided extra ground clearance under the pinion yoke and allowed me to use a CV shaft. Grinding this perch into the housing was surprisingly easy.
