Have you got a welder etc?
Bars with rod ends and make up pivot points is prob cheapest I would guess.

Yup, I have already got pivots at the moment but there not all that good
I'm tempted to get some mgf gear linkages and try them on it

I used the windscreen linkage off a Leyland National single decker and the lever off a massive lathe

Get some alloy tube and tap threads in the end, then use rod ends.
What's up with your pivots?
If they are not running on bearings alter them too or make new ones that will accept bearings

no bearings in mine, I think the trouble with it is the lower pivot might be too close to the pivot point, here's a picture
I have beafed up the rod that connects to the engine

Like what coskev said, the linkage off the bus was Ali bar with 8mm rod ends. Bit overkill but it was free, i would say get some 8mm rod, drill tap
for M6 rod ends.
Ran mine up to the top rail on the chassis and a pivot (a tube with little arms welded on at 90 degrees) and one down to the original bike arm.

I like the look of it, I'll probably get some rose joints and some bar and redo mine

Hi
not necessarily cheap but our paddle shift
works really well, nice & free (for return to center)
unlike our 1st try with a push pull cable.
good luck

If you can make up your pivots to run on bearings you get a very nice resistant free feel, also no play in the pivot points makes the whole thing feel
tighter and more positive.

Description
Dugs runs on bearings, and is very precise.
Not sure if he's got better pics, but U2U him and he'll prob take some if you want

Similar to my linkage. This one above means downshifts are on the right hand side rather than the left which I prefer.
My solution (retaining all sierra switchgear) was to mount a pivot hanging underneath the column plastic surrounds using two bearings and a u-bolt (to
clamp around the column). A bar running perpendicular to the column rotates around the pivot. One end of the bar connects to the shift rod which runs
parallel to the column, as per the picture above. The other end of the bar is a handlebar end as the gear lever. It's difficult to describe well
without a photo.
The result is half way between a tunnel mounted lever and a paddle shift. I can keep both hands on the wheel and change gear comfortably. And as a
bonus, I keep all the sierra switchgear!
