Rear disc brake swap , on Dana 44

Hi guys. I’m looking to do a rear disc brake swap
I’m running the donated driveline out of my Mexican Mav

A Dana 44 rear axle ..
I have Granada front discs. I’ll eventually upgrade them to the big brake kit

But for now anyone have any ideas on a rear disc brake swap , for a Dana 44 and it’s ford pattern

 

what Ford pattern does it have...big/small bearing?

 

It’s the usual 5 by 4.5 but for bearings? I’m not sure , how can I check?

 

if there is some way you could check and see what bearing is needed for the Dana 44 then we would know.

 

if it has the big bearing...use the Explorer rear disc.
if it has the small bearing...use the Crown Vic. rear disc.
