I'm about to embark on fitting the larger later spec intercooler to an early classic, obviously the diffuser for the early slanted intercooler is not going to work, so question is will the later diffuser bolt straight onto the underside of the bonnet? or am I better off fabricating something myself?

Cheers

 

I believe the bolt holes are different mate!

 

Looks like I'll be getting the mig out lol!
