Ducati Bevel Single Finned Exhaust Manifold Kit 250 350 450 Moto Guzzi Carburetor I believe it will also

I believe it will also work on 450

To suit most bevelhead Ducati singles and small twins of the seventies

A perfect set of engine mount bolts

and should work for all oil in frame singles and the last 500cc TR5T twin (WILL NOT WORK FOR BIG TWINS)

The card in the box with these bolts notes "pursuit lights"

Ducati Bevel Single Finned Exhaust Manifold Kit 250 350 450 Moto Guzzi Carburetor I believe it will alsoTo suit nearly ALL Ducati OHC singles of the sixties, to my knowledge. Includes special stainless nut and clamp on aluminum finned collar, fitted as shown in 2nd photo. Absolutely beautiful and functional, this kit aids cooling at the exhaust port where it's needed most and also acts as an indicator of exhaust nut tightness. Mostly though, it looks bloody bitchin'. (Note: Two exhaust gaskets likely required.)
