DIY Body Lift
 

So im out at work for the next 5 weeks & have access to a full machine shop, so Id like to put together a 1" lift for the Rover & have a few questions:
1. How big should the holes in the spacers be?
2. What size bolts to use?
3. Will 1" cause any problems with rad, shifters, etc?
Ive got a 3" RTE that im gonna install first, with extended brakelines so that shouldnt be a problem...
Ill do the body mount bushings at the same time.
What other parts would I need?
