Zetec starter motor for tiger avon

I have the new starter motor Lucas part number LRS707 and it engages with the flywheel perfectly. The only thing i had to do was take an angle grinder to the side of the sump to shave a few millimeters off of the side to allow clearance. Other people have cut a section out of the sump and welded in a plate but i found this wasn't necessary as i only needed a bit taken off.
