8 3/4" open diff. bearing journal size

[Huicho417]

Hello everyone. I am getting ready to order some parts from dr. diff to replace the bearings on rear axles and also do a rebuild on the differential. It is a 67 coronet with 8 3/4" (741 housing) open diff and 2.94 gears. On the website it asks me the bearing journal size, 1.8" or 2.0. Anyone know base on the information listed what the journal diameter is? Thank you

The open carriers and pre-68 Sure-Grips are smaller than the later Sure Grips on the carrier bearing i.d. The outer race o.d. is the same for all, which lends confusion. Any carrier fits any 8 3/4 as long as the matching bearings are used. Open and early is 1.8", Sure Grip is 2.0"

Open diff and cone sure grip. L104949 bearing. Race/cup L104912 I believe. 2.0 inch dia. The clutch suregrip has the smaller bearings 1.8 dia and the cup is 2.0 inch diameter bearing. I think the number starts with 25 I can’t think of the rest. Kim
