Yeh to mount the rear roll bar, you will need to drill holes in wishbone for the way I have explained.
Some people have only swapped wishbones, not the blocks, but then file 3-4mm off the back otherwise the car is mega_short.com.
I think Mossy has left wishbones alone but then drilled new holes for the shocks on rear of wishbone, so nothing other than shocks has changed. Apparently the method above gives better forward traction than this due to swept forward driveshaft angle.
The way I have done it is somewhere between these two. Will be giving it a thrashing on Saturday. I haven't seen anyone achieve rear shocks with my method yet either.
An unmodified car is still excellent. For example Grant Williams was in the A-final at Oswestry with his car unmodified. So its all down to personal taste. Don't just follow a trend like a mindless sheep thinking it is necessary, as it isn't always.
