Nick, there's nothing available off the shelf for the cars i'm afraid....this is what its like when you own a Viva!!
You can buy Spax adjustable shock absorbers off the shelf...but you need to order a set for a Jensen Healey...they are the same as the Magnum/Viva 1800 & 2300 shocks.
As for the coil springs....i have a set of fronts from my snoot which i could use as a pattern to have some made......the back set wont be coming off until the restored front end is put back on, so would be a wait for the backs, or take yours off and get them made an inch lower. There is a company in Chichester, 25 miles or so from me, who make springs.
Price wise, expect around £60-£70 a corner for a one off set of new coils.
The springs with the Spax would make a nice set up for the car...sorting out the wallowing and dipping....plus some decent bushes in the rear arms, front suspension arms, chassis and outriggers.
Not a lot of change out of £750 for that lot i reckon.....have you got a large hammer to shatter that piggy bank with!
