Review on Yukon GM55P 308 Performance Gear Differential by Michael Boyd

looks good but doesn't fit 56 Belair. I had to move the carrier to the left in the third element enough to get the correct clearance so that the ring gear would hit the back of the case. Heated and pounded the body to release and mounted the differential. The creature howls like a coonhound. He pulled it back, the left axle hit the transverse shaft. I replaced the 355 cog with this one and hoped for the best but no luck.
