Mondial Bushes

Quick question for fellow Mondial owners. The time has come to replace the suspension buses on my Mondial 8. I don't particularly want to go through the rigmarole of grinding off the existing welds and tack welding in new OEM bushes. Powerflex sell bushes here in the UK that don't come pre-bonded - do you think these would do the job of replacing the innards once I've pressed them out? think https://www.powerflexsuspensionbushes.co.uk/powerflex-front-upper-wishbone-bush-pf17-200-for-ferrari-mondial-8-quattrovalvole--32-118082-p.asp
Energy Suspension in the US don't seem to sell the inner parts any more, and the Superformance bushings sold here look like the inner rubber is also pre-bonded into the metal casing.
Thanks in advance for your feedback!
