Steering column advance / throttle tubes

[ollyS]

further to first post and other replies here are few pictures and details
the outer original tube with car and has thrust bush on end Part BM136 has OD of .561 and ID of .360
The first rotationg tube brass and part bm130 has OD .497 and id.401 ---- this is problem as will not fit into above part.
the final inner brass tube ( which fits above) Part bm129 has od .375 and id.320

Any idea's

If any of my parts don't fit, it would be really helpful if I was told about it direct instead of happening to come across it on the forum! Then I might be able to do something about it. I usually supply all the three tubes together, which do all fit together nicely. This is the first hint that I've had that there might be a problem with them. I think the 9/16" outer tube I am getting is thinner than the original, and the 1/2" tube is thicker. I will see if I can get some tubes which are more like the original ones.

Firstly may I say apologies for any upset I have caused.i have only ever had excellent advise, help and parts from David and I hope this has not been taken the wrong way.

When I tried to fit the tubes I was confused and thought it an interesting deviation from the norm. I was thinking and still am that it is an anomaly with my set up - I was hoping it may be a bush or something that had been added.

I am not about today but will call you (David).
Apologise again
