Hi thanks for your quick reply’s.
I’m based near portesham so not too far from either of you two!
with regards to 4 1/2" tube I can get it for a price in 10 SWG ( about £90 if memory serves). however according to the drawing i should remove 3 thou from the i.d would it be worth doing this or leave it as 10 SWG?
