Roto Flex problem

[wculbert]

Hi,
I have a Rochdale GT with Triumph Rotoflex suspension. Yesterday it failed it M.O.T dues to one of the couplings being split.

Do you recon that it would still be good for 2,000 miles?

What danger is there in still using the car as it is?

Is it easy to replace, could I do it myself?

Could one glue it back together?

I hear that the replacemnt donoughts come in two types orginal and reproduction, the original ones are twice the price, are they worth it?

Thanks William Culbert
