Hello mate .i am in the process of finishing my mk1 frst,what do ya wanna know?
You will need to convert the n/s chassis to fit the escort box as it is too long,you can use a mk1 xr2 engine craddle and i am using vibra tecnics mounts,and the same as the mk2 you will have to cut the front cross member to make way for the down pipe, i also cut the centre of my front valence out to fit a frst rad if thats the route you wanna take and i had an intercooler made to fit the rest of the hole left in the front panel.
hope this helps
mark.
