Need some insight. 8 3/4 742 sure grip center mid 60s & B body rear (68 charger donation) Green axle bearings - so no adjusters on the ends anymore Can we pull the thrust spacer out? It is not a cone style diff. Problem we are seeing with the thrust spacer in: The second axle to be installed will not fully go into the carrier. 2nd question: How does one remove the thrust spacer? Don't say sledge hammer!
