Just sold a month or two ago my personal use custom Clearview with the Triumph 3 bolt chrome strap TT from the 'Summer' smaller screen but it easily carried the larger Custom Clearview screen. Usually the bigger Triumph screens came with the 5 bolt chrome TT strap mounts.
Ye, I still have a spare large 5 bolt chrome TT strap and side brackets kit with the 4 fork clamps and a couple of Triumph large 5 bolt screens.
Std Air Postage to USA is about US$100 with a screen fitted from Australia and I have sold and sent quite a few around the world before. It is a lot of work to dissassemble and put back together as there are about 16 little metal spacer tubes that fill in the space between mounting bolts, TT straps and holes in the screen. These are also positioned under the rubber strips that fit between screen and chrome TT straps. It doesn't look like it but there is definitely a right and left TT strap and get them wrong and it will all seem like it should fit but wont. Lessons well learnt and I avoid pulling them apart now as it takes hours to reassemble.
If your making a trike and want rear passenger footboards you can actually use the Triumph ones from the single headlight Rocket III Touring (R3T) models.
On dual headlight Std/ Classic and Roadster Rocket IIIs there is a 2nd mounting hole each side of frame under the chrome covers fwd of the single rear peg mount hole.
This is the
exact same spacing as used for the R3T rear pillion f/boards. You will need to either leave the chrome covers off after fitting or simply drill a 2nd hole in each cover and shim/spacers to fill the space between frame and chrome cover so it does not deform when the footboard mounts are tightened.
The other advantage is it places the footboard more fwd than singkle peg so an extension bar is not needed like with aftermarket solutions from RIVCO to bring the pillion foot position fwd.
The R3T REAR footboards are fairly common used from Pinwall wreckers online or eBay as they rarely get damaged in wrecks and VERY IMPORTANTLY are symmetrical and FIT EITHER side of motorcycle so you do not need to buy in L and R pairs but can pick up separately either side to make a pair. I think somebody was selling some on the forum classifieds recently too.
