Base on his more than 45 years experiences especially at Montreals , I am 100%
sure that he knows exactly how to remove head bumpers at Montis. Most probably only "a piece of cake" for him
If Gachnang is not too far away from u , I recommend to go to his garage directly .
I am convinced that he can remove ur bumpers within shortest time and u can join
during this work. So you know afterwards how everything works.
Sometimes its cheaper, more safe refer to own produced damages and less time consuming to involve
I know J. Bürgi since more than 12 years and I was and I am always satisfied with his work on my Montreal.
