There would bo NO bodywork modifications necessary at all, it will just bolt in place of the normal bracket that carries the cross-over tube on the front of the predal box in the engine bay. It might be necessary to remove the brake pedal and drill a 8mm hole in it to attached the pushrod clevis, thats all. The two reservoirs would be mounted under the bonnet near the wiper motor I would think.
Hope this helps,
Martin
