65 dart revival

318 got pulled out yesterday, the 904 as it turns out was out already in the trunk so only 20 minutes to pull it out. The intake on the 318 was a early 70s 2 barrel single plane we took the 2 barrel flange off and opened it up for a 4 barrel and bolted a carb adapter 2 the intake. Did that almost 30 years ago. 4 barrel on a budget. Looking at the brake options, We have 2 possible donors a 72 b body disc brake front end and a 75 dart sport disc brake complete front end... Or could go with new? My question Is the 72 b body worth using? Or is the late big pattern A body caliper style preferred.
