Cut outs in under bonnet the sound deadening felt
Paul Smith posted a note on the V8BB seeking information on the location of the cut outs for the tops of the SU carburettors and for the nearside of the radiator. (Jun 09)

Paul's query was "has anyone got the correct position and dimensions of the cut-outs for the radiator and carburettors in the under bonnet soundproofing panel?"

Taking measurements from the felt panel on his Factory MGBGTV8, Victor Smith produced two drawings which are alongside. He notes "the circular cut outs for the carburettors are 6cm diameter but I think it would be wise to cut them as 8cm diameter just in case my measurements taken under the bonnet are slightly inaccurate. Having the cut outs slightly larger will not be a concern unless you are seeking a concours finish!"
