ok for the tech questions:
Firstly for damage parts, The arms and beams have there own jigs so should there be damage the can check for straightness or remake the individual parts, Replacement adjusters etc will be stock items.

the beam in the pic is a stage 1 so thats camber adjustable and to set rear tow we slot the outers and tack weld big penny washers once set and tightened, Same as Mike R mentions in another post which is what group N guys do.
The angle between pic up points in 6 degrees, we tried others and yes rainbum is right again 6 degree is optimum.
stage 2 will have FUll adjustment with inner and outer rosejoints.

Granada: Mk1 fastback, LS1 5.7 alloy V8, Custom long tube headers and exhaust fabricated and Go-Tech engine management, Cossie Rear beam is next on the list for install with a 9" diff gearbox is a tremec T56.
