I'm looking to service the Borg Warner 35 gearbox in my 1973 P5B Coupe. It's not had an oil change for at least 5 years (7000 miles).

Where's best to get all the bits in one kit, gaskets, filters etc?

It hopefully won't need to be rebuilt or stripped right down, so only the bare minimum required please.

The BW 35 was also used in the Jaguar XJ 2.8 and Mark 2 and the Volvo 164 so check in with Jaguar and Volvo specialist. I've seen the filter gasket but not the filter itself. Most are now selling inline filters.

Wins or Wadhams I would have thought.

My BW35 in the Estoura is leaking, which needs to be addressed at some point.
