Martin #1458 #4426 and working on #2292 all weekend. Tired.
Are two big sheets of aluminum where rear wye spreads out. TAB's above them. You may end up cutting the 6 mounting bolts (riv bolts?). Were attached to fiberglass when new but seem to spin free with age. Plus are carbon steel wonderfully prone to rust (how 'bout that "rust proof" DeLorean!). I replaced with 1/4" stainess steel bolts and fender washers. Car is small enough you can reach bolt head and nut by yourself.
