Carb Overflow Pipes

[Larry Swift <mgtd51@adelphia.net>]

My car - a 1959 BT7 - came with stubby overflow pipes with short plastic 
tubes attached to them.  According to the concours guidelines, the 
Anderson/Moment book, etc., the pipes are supposed to pass through a 
hole in the heatshield.  I believe this means that the rear overflow 
pipe takes a right angle below the carb, passes in front of the heat 
shield and takes another right angel to pass through the hole in the 
heatshield.  The front overflow pipe looks like a straight shot down 
through the heat shield hole.

Would someone let me know if this is correct, or if not, the proper routing.

Also, how far down the side of the engine should the pipes extend.

Thanks very much,

Larry Swift
