I thought the same thing the front springs are probably the same as the fwd mk1 Mondeo
Identical parts may have different part no.s to disguise thier origin - the 4x4 Jaguar x-type may use some of the same parts as well- there is a member (moderator?) of another forum that ran a 4x4 16v mk1 for years, perhaps he can help you with advice/ where to get parts (i hate reffering to other forums sites) - its called talkfraud (or something tike that )
There is someone who has transplanted a 5-pot 2.5 Turbo ST225/ RS/ Volvo engine into a mk 1/2 Mondeo 225Hp out of the box, 280+ just with a remap and potentially 350+Hp with a bit more work - this may be a more cost- effective way to get more power in the long run (depending what your goals are)
Again hate mentioning other sites but there is one called passionfraud (or something similar ) that has a lot of build threads / engine swaps etc and a lot of members with highly modified cars etc
You could start a build thread on here (there is a new "build thread" section) perfect for you, it won't get lost amongst all the 400+ Hp Cosworths and you won't get the jealousy/ "bitching" that seems to go on on other Car sites/ forums (this is a "nice" site - with genuine Ford/ car/ modification enthusiasts )
+ you would enhance / boost the build thread & site with your rare/ intresting build
Im glad you decided to keep your 4x4, good luck with the build, looking forward to reading about it/ seeing how you get on!
here is mine -
