from bearing face's on axle is 50'' and 54'' from halfshaft faces
Then it sounds like a european mk2 escort, the same as mine, they measure about 53 1/2". Ratios are usually 3.89:1. Mine is 4.11:1!! Or could be from a mk 1 capri.
Getting rare now, and known more as the baby atlas, a lot of people think these only came from mk1 capris, but they did live in escorts too.
