I think they are about that Clive - and you will want new ones if you are fiddling with any of the plumbing at all, they just snap of in yer hands it would seem Years of life probably making them brittle loike...
Try getting a tank out when someone has driven into your rear corner at 40-50mph and bent the chassis rail into it... needed quite some persuasion with a 3 tonne jack.
Everything else is out anyway, the tanks the last thing and there's a hole up behind there I can see, was going to let it go, but think I'll get it out and then that'll be it, start welding it all up and putting it back - been practising my welding on the Doka steps and sills.
Those rear cross-members were indeed full of silt after wading up in N. Herts. but not rusted through.
It is possible to remove it with engine in place no problems. To be honest, I don't see how removing the engine would have made it any easier.
Cheers,
Sam.
