the cutting and welding of the shift lever is to make it closer to working with the stock shifter "can". What Gerard offers is a modern upgrade/repro of the no longer available gaiter ring that came with the later 1500 cars. An elegant solution to the relocation of the shift stick...
As an aside, Gerard is one the "good guys", ala PPP Hap, Jeff, Paul A. Quality, reliability, S.O.P.
