Availability of the b/e ones are more plentiful,a body ones are more scarce and pricey,and if you already have the b/e ones laying around why not put them to good use,not everybody including me can just run out and buy all the parts for an a-body set up or can find them readily,this bracket has been around a long time glad to see it revived and works great,we need more a-body 4spd cars,and it's not much work,pretty simple and straightforward..oldschool ways still get the job done...
