47-55.1 Anyone running Under Dash Brake/Clutch MC?

[Dongray]

Ive been considering an under dash clutch and brake MC setup but debating on whether the 90 or 180 degree system would be best. I was wondering if anyone on here had used either the Scotts Hotrods or Kugel systems and what they thought of them? Im really interested in finding out which setups will still allow you to retain the cowl vent operation and the wiper motor. Ive searched this forum and there is a fair amount of discussion but most links to pictures don't work anymore. It appears that a 90 degree can even include a booster but wonder about cowl and wiper operation. Thanks
