Can any of the Astra GTE 16v engine mounts be used for fitting it's 20XE into a Corsa, will the Corsa ones do, or do they all need replacing for custom items?
you use the standard corsa gearbox ones
make your own o/s chassis leg mount yourself...
jack the engine up to a position your happy with, connect the linkage 1st, find all gears, make a cardboard template of the holes, copy onto 4mm sheet steel and then weld solid, reuse your corsa bolts to fit the mount and its job done.
pm me and i'll let u know about a friend who makes them for the corsa (made mine).
