Single speed conversion to Coaster Brake

A friend has a road bike he converted to coaster brake.
I am interested in doing the same with my 2009 Fuji touring bike converted to a single speed.
I would like to make it have a coaster brake.

I looked at this:

Shimano Coaster Brake/Alex DC19 Rear Wheel

Coaster Brake Series Rear Wheel
Wheel Size: 700c
Rim: Alex DC19
Rim Color: Black
Hub/Brake Compatibility: Coaster
Tire Type: Clincher
Cassette Body Type: Single Cog Driver
Rear Hub Spacing: 124 mm
Rear Axle Type: 3/8" bolt on
Skewer Included: N/A
Hub Drilling: 36
Spoke Info: DT Swiss Industry
Spoke Color: Silver
ISO Diameter: 622 / road / 29"
Rim Material: Alloy
Valve: Presta
Valve Length: Short 32-40mm
Rear Wheel Type: Single-Speed
Weight: 1,180.0 g




but the rear hub spacing is 124 and I believe my Fuji is 130mm.

Any other options?
Can I jury rig this wheel and hub?

Thanks,
Alan

If the axle is long enough, you can put spacers on each side to increase the OLD to 130mm to match your frame. Make sure enough axle protrudes through the dropout to fully engage the nuts, though. Or you can cold-set the frame down to 124mm to match the hub (assuming steel frame) and align the dropouts so they're parallel again. Or live dangerously and use the hub nuts to squeeze the dropouts down to 124mm spacing without cold-setting. This carries a slightly higher risk of axle failure as the dropout faces will be slightly out of alignment.

...I just recommended the SRAM two speed hub to some one else and am using one on a track bike build to get around the not drilled for brakes on a track bike thing. You can buy them with or without a coaster brake, and run them either 120 or 130 spacing.
