Hi All,
When redoing my Healey back in the mid 1980s, I was suspicious of the condition of many of its rubber-bonded parts (i.e. motor mounts, transmission mount, rear rubber rebound bumpers, exhaust mounts) but, after a close examination, only needed to replace the smaller exhaust and transmission mounts and just refinished and reused the rest. Since the internet was not as vibrant at that time, finding information and capitalizing on the experiences of others was not an available option. As a result, it was not long before the rubber in the new exhaust hangers began to separate but the original motor mounts and rear rubber rebounds remained good to date.
As a result of the many failures of the newly acquired parts, I began to modify, rather then replace, the separating/separated hangers and mechanically reinforced their re-glued rubber components. This approach seems to have worked to maintain positive rubber connection although it did reduce original flexibility to a small extent that did not seem to hinder its function or transmit any vibration. The approach taken to mechanically reinforce the rubber attachment of the part was dependent upon the direction and expected extent of needed flexing and simply consisted of setting a screw through the metal mount and into the rubber and secured with glue. Although this approach seems simplistic and I can't say that the re-glue would not have held on its own, the repaired parts have not failed in the past 20 years.
Although I would like to state the glue used, however, I have not found my documentation and, sorry to say, just do not remember. I believe Obrienwm's post is a good lead for acquiring an appropriate adhesive.
