                  the profile of an MGB bonnet changed for the MGBGTV8? 
 As a double-check we are getting two members 
                  to measure the curvature of an early MGB bonnet and that of 
                  an MGBGTV8 bonnet and will report their findings as soon as 
                  the data comes in. Measurements

 A recent query from a member said "I seem to remember reading 
                  somewhere, some time ago, that the Factory V8s had a reprofiled 
                  bonnet (greater curvature) to aid clearance over the carburettors. 
                  Is this correct? I believe it was subsequently introduced on 
                  the four-cylnder models too."
 
 We contacted V8 member, Peter Beadle (formerly parts manager 
                  at University Motors and at Moss Europe), who said the earlier 
                  aluminium bonnet, part number HZA401, was replaced by a steel 
                  bonnet HZA4015 for the MGB and GT models and then later HZA4197 
                  was introduced for the MGBGTV8. In the Parts Manual AKM0039 
                  (see extract below) those two steel bonnets were replaced by 
                  HZA4014 with a note you need the mounting bracket BHH1934. So 
                  far as he is aware the profile or curvature of the bonnet did 
                  not change although there were cut-outs in the sound deadening 
                  panels above the two SU carburettor dash pot tops to provide 
                  headroom.
 
 Peter recounted how, when he was at University Motors in Epsom, 
                  he heard there was a stock of V8 bonnets with a distributor 
                  in Ireland and found they had no demand there for them. So they 
                  were shipped over but on arrival they each had spot damage on 
                  the bonnet. Why? Well HZA4197 had the mounting bracket for the 
                  bonnet stay fitted and when the bonnets were stacked one on 
                  top of the other, the protruding mounting caused damage to the 
                  bonnet below in the stack! So HZA4014 is supplied without the 
                  mounting attached and the Parts Manual has the note you need 
                  to get and fit BHH1934! By the way Peter says the damaged V8 
                  bonnets were sold off as seconds.
 
 Peter mentioned another point and that is most V8 panels start 
                  around HZA4600 so it seems the much earlier HZA4197 part number 
                  for the V8 bonnet suggests it was first made before most of 
                  the V8 parts.
