#61708

I got my bell housing now. As V8 Tiger says, there is not much thickness of material to cut a thread. I wondered if there is room for putting captive steel nuts behind the new holes, mounted on a retaining plate? That I could do myself without specialist Alu welding.

One other thing no one mentioned, the damper on the 260 is a three bolt fitting to the pulley. If the new engine is a 4-bolt damper (post 1971?), can I just re-drill my Tiger pulley to fit the 4-hole damper?
