Hey there I have a rotary aviation OMP adapter and about to install it but i dont want to use the Sohn type setup. It wastes alot of space, and seems the bottles used are just $10-$20 off the shelf types and look like crap.

There is a fair amount of room to fit a bottle between the drivers side strut tower and brake booster (10cm*10cm*25mm gap which opens up wider at the bottom where the inner guard is). Has anyone fitted a bottle there and if so where did you get it or was an off the shelf type heated and molded to fit?

There are plenty of posts about the OMP adapter but nothing on alternatives to the Sohn or using other adapter bottles/reserviors...

Cheers
