They're potentially the same, but your link doesn't give spring dimensions.
Save the six quid and buy the ones I linked to Decent seller, have used for several items over the years
looking at both, the £65 ones are "Coil Spring With Constant Wire Diameter" the cheaper are wit pigtail ends ,as per carlton (which snap ,and is a fail mot wise)
the same problem with astra G estate , the newer "Coil Spring With Constant Wire Diameter" don't loose the pigtails
plus the postage is quicker on the £65 ones
But thanks for your input DG
