This happened to my IIIAs, many years ago.
Given the glue failed once ... I didn't want it to fail again. So I drilled a hole through each end of each bar - and through the metal driver-surround - and used 4mm (5/32", in your language!) bolts with a spring-washer, to clamp the bars tight, permanently.
Mind you, if you do this, you need to tape A3 sheets of paper both sides of the driver, to stop drill-scarf from getting onto the mylar or into the holes.
