The 2Cv’s exhaust cross box is hung off bolts that go into the gearbox casing.
This does the job of holding the cross box in place – as well as the brake “cooling” ducts – but it is somewhat awkward to assemble everything together. As with the fuel pump and engine breather, the SPOG make a set of studs to replace the bolts to make assembly of parts easier. Fitting is “simply” a case of removing the old bolts and screwing in the new studs. The catch being access, even with the wings removed it’s hard to get to this area – especially to fit the studs – with the exhaust still in place.
With patience, perseverance (and some swearing) the studs went in and the exhaust cross box and brake ducts were secured with the supplied nut and washers.
Of course, the real key to the operation was the supervision of the car’s owner.
