Frank, you should be able to use a length of 38mm ( 1.500" )OD tube and run it thru a swage or a set of rollers with double VEE formers to slightly square the tube & allow it to fit--- 35 x 4 = 140--------38 x 3.142= 120mm. Then once fitted to chassis use a pipe mandrel/expander to return to round shape.
Try it on a piece of scrap tube first. |
