as I bought it (with half a dozen CEL codes, a dead ABS system, a few dozen electrical faults, blown shocks, and a questionable head gasket):
In it's current state and it's natural environment, 237,000 miles and counting on the chassis and bottom-end
Honestly I've done more reading and I've got the wrong brackets. I thought the Maxima bracket part number carried forward, but it's apparently only the '81 cars that come with the brackets where the bolt "ears" are offset correctly.
I'm now debating either buying some fab'd brackets from one of the vendors, having a friend modify these, or looking at going ahead with a 5-lug swap....although I'd like to drive the car in something close to a stock state before I go changing a bunch of stuff.
