Hi, I am converting my herald 13/60 to rotoflex back suspension and have bought a complete rotoflex set up from a mk2 vitesse.  However the rear spring is knackered so I was wondering if the good rear spring from my herald would fit the rotoflex system.
Cheers Andy

Don't see why not.  Certainly it will physically fit.  IIRC the Mk2 roto spring is the softest (lowest rate) with Vit Mk1 and Herald being the same.  You can always fit a lowering block if it sits too high.

What are you going to do about the handbrake cable run?

Do you need the rear spring with the bent under bits as the usual shackle hits the rubber couplings?.

Thanks for the advice I haven't really thought about the handbrake cable yet but I have got the whole rear end of the vitesse chassis so I have got all the brackets if anything needs swapping over.  I'm planning to do a cv conversion so the couplings fouling probably wont be a problem..

Hello Andy

You may need to consider moving the hand brake guides as well to avoid the doughnuts.  I believe the Rota flex cable is longer than the non Rota flex cables.

If you are doing a CV  conversion it doesn't matter a damn. Just use the one that fits!

It's worse than this.  The geometry of the swing axle handbrake cable guides doesn't work well with roto (doughnuts or CV) and you get a handbrake whose adjustment varies with suspension position.

Colin's comment about the "bent under" bits shows me that I have a Mk1 spring fitted on my roto (CV) car.  And yes, they did used to catch on the doughnuts when I still had them - not a happy noise......

Looks like i will have to transfer the cable guides from the vitesse chassis to my herald one then.

Rotoflex handbrake cable guides are on the floor beneath the back seat, not on the chassis.

When I converted my 13/60 to rotoflex I too used the herald spring. The clamps on the spring will indeed make contact with the rotoflex coupling, remove the bolt and bend them under. Lowering the rear will make the issue worse.
the hand brake cable issue, i solved by using MG midget cables with a retaining plate mounted to the underside. The cables are of the bowden type and can run in an indirect route.

Ah right I didn't realise that I might have to go with the midget handbrake cables then.  I've also got the complete rotoflex driveshaft's, hubs and lever arm shock absorbers to get rid off if anyone wants them.
