Weighed my Duster!

I had the opportunity to weigh my 73' drag car the other day. Unfortunately I didn't have time to tweak anything. Only fiberglass on the car is the front bumper. Aluminum headed small block and Strange disc brakes up front with a full width S60 outback. No inner fenders and everything else pretty well gutted to the max. Still has back glass and quarter windows. Pics are without me and with me and my gear.

How much do the front brakes weigh compared to the factory 73 + disc set up ?
