Hi Wirewheel

That is something we could look into, or, if any customers know what their threads are, then we can add to the kit to suit at an extra cost.
Once we get some idea of other threads on the Morgans, we would be happy to help by putting adaptors in the kits to suit.
Its not so easy with the metric side, because most of our metric adaptors are, imperial female, metric male.
But the imperial side, 1/8"bsp, 1/4,bsp etc, can be easily rectified.
Any modifications to the original kits will incur an extra cost as mentioned, but I agree, its cheaper than the thread gauges.

Always willing to help with any questions or queries...
