At the front of the car the MGB GT V8 front crossmember was installed, which has a 3/4" lifted perch. The front coil springs were also taller to get the car up to the required Federal ride height.
At the rear of the car, both the front and the rear spring mounts were extended down from the frame and the spring has a bit taller arch. It is interesting to note that the chrome bumper MGB GT V8 had extended front mounting points, but standard rear ones.
The springs were also stiffened to handle the extra weight of the rubber bumpers.
There are a number of different ways to lower the car, but keep in mind that since the mounting points have been moved, if you lower the car to the same height as a chrome bumper car, you will have less suspension travel and the car will not be as usable.
The easiest way to lower the car is with a set of front lowering springs and spacer blocks on the rear. We installed these on a 76 MGB owned by our technical specialist and the change in handling was pretty remarkable. I would honestly recomend them, as it is a pretty easy job to do at a good price. The parts are all listed at http://www.mossmotors.com/Shop/ViewProducts.aspx?PlateIndexID=34772 This kit will bring your car down to approximately chrome bumper height depending on how sagged the rear springs are.
Another possibility is installing a chrome bumper front crossmember, but this entails playing around with steering geometry and is not something I would recomend. The rear spring mounting locations can also be moved back to chrome bumper design, but this requires major fabrication of the mounts and the bump stop support.
For the front there is also a lowered king pin assembly available from specialists. It will lower the front end one inch without changing the geometry. It is an expensive option, but something to be considered as an alternative to changing the front subframe.
Hope this answers your question
