..the "new" Butler modified MGB has: coils AND shocks---but they're not coils-over-shocks---the shocks are on separate tags welded to the upper A-arm. There are Wilwood 6-pot calipers and these require (sometimes) a wheel-spacer so 15" rims clear the large Wilwood calipers. The old ones had this weird piston-and-reservoir doo-dads on top of the upper suspension arms. These are strange but work perfectly(?!), albeit they needed pedal-travel adjustment..
I'm off to God's Country (that's Maine for us Easterners)
for a week or so. After that, I'll photo and post the two axels. The new one is already in---but the old one's in its "coffin" ready for shipment, if someone wants to buy it.
