8 1/4 Rear Installed, now about that Carrier...

I have installed a '76 8 1/4 from an Aspen Wagon into my '85 M Body. Fit was perfect. It came with a 2.71 gears and ran it around for a coule of hundred of miles. On E-Bat, I bought a Dana-Spicer Posi(Is what they called it) unit pt# 75101x. It fits ALL 8 1/4" with a 27 spline axles. I bold the "all" since that is waht the ad said. Vendor is GearsAreUs. I also bought a set of 3.55 gears with the carrier.

Anyhow, the pinion when in smoothly as did the ring onto the carrier. However, when I try to install the carrier into the housing, the pressed on bearings the I pressed on myslelf, are too large in diameter to fit into the Bearing Caps. The rebuild lit from Motive Gears, pt# R8.25 RMK says it fits all 8.25" Chryslers. kit came with carrier bearings, Pinion bearings and seals. Pinion bearing fit nice along with the seals. It is just that Damn Carrier bearings being too large.

I try to put the race inside the Cap and it looks like the race is about 1/8" to large in diameter.

What the heck am I doing wrong?
