Mk1 Lotus twincam escort HELP

[Bunky Twincam]

Hello all,

My original single hole twincam front cross member is a bit old and tired so I was thinking of fitting a Burtons front cross member.

However I have been told that my engine will no longer sit with a bias to the left and that my starter motor will hit the steering shaft from the column to the rack. Can I space the mount from the block to get the left bias?

Is this the case and if so is there one available to suit the twincam?

Also what is the best air cleaner to use?

Thanks
