i heart haters

I'm in the process of doing a solid axle swap on the rear end and about to order the housing and axles. I've only been able to find the rear track length for an FD RX7 (1460mm) but can't find anything on the stock axle width (yes I've used search and spent a day looking for the info elsewhere). Does anyone know what the stock axle width is or have a rear end they can take the measurement on for me?
