37 ford rear axle

[marshall k]

greetings everyone-trying find if the rear axle in my 37 is right for the year. the spring hanger perches are welded to the axle housing and rad rods are bolted to the backing plates, which by what i read should put it to a 37-41 housing. however there is no fitting to lube driveshaft support brg which i understood to be a 37 inprovement. serial number puts it to a mid-year build. anybody ran across this before? thanks for your time.
