replacing cobra holders with t'blades

[avb 0]

I hate to start another t'blade topic, but I couldn't find the answer in any the old threads...

Do any of the mounting holes in a t'blade match the holes in a cobra holder of the same size?

Or do the RMS nuts need to be moved?

no the holes arent the same. to mount the t-blades they have to be remounted and re drilled
