I am the proud owner of a ...Mark 6? Long story short it is a Mark VII 'body' with the top half of a Mark V headstock attached to the bottom half of the Mark VII (still has reverse). I still have a lot of the 7's spare parts, including the cam-less speed control, so I suspect this was a previous owner's solution to a broken cam.
It came along with all the original advertising materials, manuals and parts list, if anyone doesn't have the info and needs it, I can scan it.
My question is, did anyone come up with a replacement belt analogue we can find at a car parts store?
I need to replace the main belt, part 507490

First determine the motor/idler shaft spacing on your 'mixture'.
Then calculate the belt length. If you follow the entire thread you will discover a reasonable priced belt available in 1/2" increments. Also a way to determine if length is correct(belt position on pulleys at speed extremes).
If you do not mind, share with us the idler shaft/motor shaft spacing on your 'mixtutre'.
