Hydrolastic ride height and helper springs

My 66 Morris with wet suspension rides higher in the back. Always has. The front suspension has been rebuilt and I have installed the progressive bump stops all around. I have the shocks for the front also but have yet to install them. If i pump up the suspension the whole car gets higher but it is still a good 1-2 inches higher in the back

I was wondering if part of the helper springs role was to counter act the weight of the engine over the front of the car and hold the car level. Is this correct? Without them I would imagine that the front suspension would just bottom out under the weight of the motor.

If this is the case would it be possible to buy new springs, shorter/stiffer springs or modify it in some way? Or is there something else i am missing. Cheers,

I just found this,

In my research I have read that there are shorter springs and longer ones. Am I right in thinking that the pre 66 are the longer and the later springs are shorter?

you can also machine the part that goes between the knuckles and the displacer to lower the car, or space out with washers to raise the car up.

Yes, I have read about this. I think i will give it a shot. Anyone got a spare set of those rear hydrolastic struts to machine down?

Excellent, but how do I know if I have an early or late car. I would assume I have early being 1966. Thanks,
