The m55 and M75 resonators are different. Although similar, on the low side of the M55 resonators, there are tabs that engage the rubber mounts on the frame (sort of looks like an upside down “L". On the M75 they are straight. Also the front M75 Resonators tubes are longer. I’ve never measured both but I thought it may be possible to make one or the other fit, but it would require some cutting, welding or both.

Check out the manuals here for each vibe, you’ll notice the resonators have different part numbers.

Thanks . I guess this difference also applies to old M75 models, like 60's , right ?
Yes

The M75 design hasn’t changed much in 40 years. I’ve never seen a tabbed version of the M75 resonators, and All M55’s I’ve seen have tabs.
