Help choosing an air fork

[PCeBiker]

I'm thinking of buying an air fork but I'm having trouble finding something that will fit.

I have a 26"X4" fat forks with a 135 mm drop-out.

They are the TNL 26" version with the coil spring and the hydraulic lockout, 75mm of travel, and 1.5" to 1.125" tapered steel steerer tube.

I want to get a double shoulder downhill fork with as much travel as possible but my tapered steerer tube and 135mm dropout is limiting my options.

I like these and they are nice and cheap (I don't want to put a $10 saddle on a $2 )
$118 plus $59 shipping.

But they don't come with a tapered steerer tube, so I'm thinking of getting a 30mm to 38mm steerer tube/bearing shim.
The top of the steerer tube is 28.6mm and the bottom is 30mm.

Does anyone know if such a shim exists?

The closest I've been able to find is this,..

I'm thinking that I don't want a split shim?
I think that I want a one piece steel press on shim?

Does anyone know if such a beast exists?

I can get a downhill fork with double shoulders and a tapered steerer tube but it has a through axle and seems to only be available with 110mm or 150mm dropouts.

I took some pictures of my steerer tube when I installed my handlebars but I didn't take measurements,..
