Thanks for the praise.
we drilled out and tapped two of the holes that we could make work and put factory bolts in. the other two holes require welding to build a area.
It is close but still half a fingers gap away from it. there is a bolt on the sump thats close to rack on passenger side we just ground the head down for extra headroom. the engine twists away from it anyway.
I can get pictures of the setup. basically its just a plate that you bolt to the firewall with bolt and nut, then two holes tapped out that bolt the stock cylinder too. Made up a new clutch rod too. The pedal feel is no different, we suspect that the booster never worked in the first place but it is no different to any other car with a multiplate clutch in it.
If your doing the conversion and have a stock plenum you might not have any issues just the hypertune manifold is alot larger he standard
