Jarl, OK, you trumped my ace!! Your experience is better than mine. I owned
a 53 TD in 1958 but can certainly not remember any details on the overflow
pipes.
Anyway, I checked 12 TD/TF front bearer plates in my possession and they
ALL had the hole that you say was used for the overflow pipes. I then
checked 6 TC front bearer plates and NONE of them have the hole. So I guess
your routing could be correct for the TD, but the TC had the pipes over the
top.
However, I checked with an original owner of a 53 TD about the routing of
the carb overfl;ow pipes. The engine has never been out of the car, but the
carbs have been off and he states FOR SURE the pipes went over the top on
his TD. The hole is also present on his front bearer plate.
So why did MG install the hole?? possibly to route the pipes through as you
say, but it appears that at least some TDs were built with the pipes over
the top. Also, of course the TC.
Anyway, I think the original question on fastening the pipes has been
answered.
regards, Bob
