Rear axle defender 90 vs 110

Does anyone know if the 110 24 spline Salisbury rear axels can be used on a D90 with hd flanges and rover 24spline diff? The part # are FTC1724 and 1725.

The 90 rears with the attached flanges measure 26.25" and 36.75" total lengths including flange.

One site in the uk had dimensions on the 1724&1725 as 25" and 37.6". Seems like to me the diffs aren't centered the same but there is mention of narrow flanges which may make up the difference?

I know a friend of mine told me he runs 110 shafts on the front if his classic but I am not sure about the rear.

Any guidance would be greatly appreciated!

I highly doubt it.

Salisbury carrier is much larger than the Rover unit.

Could the difference in width between the diff be compensated for by the shorter shaft on the one side?

He is talking about axle shafts. They are the same spline, but different lengths. Even disc to non disc sals are different lengths.

Nope they are different on one side for sure. If it an older truck with drum brakes the axle shafts are 3/4 of an inch longer than the disc brake sals. Also the drum brake sals run wet as the stub axle doesn't have the seal and the axles do not have the raised portion for the seal.

It would be disc brake Salisbury axel shafts to a disc brake rover rear.

Absolutely the short side sals is shorter and I forget if the long side is the same or a bit shorter too. The Sals shafts are a thicker diameter like some of the aftermarket HD shafts.

Best comparison between the two is think of the 90/d1/RRC having a Dana 44 size axle and the Salisbury as the Dana60.
It's called Salisbury because it was made in Dana's Salisbury England factory
