1958 Corvette Seat Frame Removal?

[MosportGreen66]

Hi Gents,

Putting an interior in a '58 Corvette. The car's seat adjusters are frozen to the seat frames. Here is the problem... there are four bolts directly beneath the seat frame I need to remove in order to physically remove it from the interior.

If the adjusters engaged, I would be able to slide the seat frame + adjuster forward enough to remove these four bolts. But since the adjuster is frozen to the frame, I cannot slide the frame on the track. I tried spray lube and a hammer - did nothing.

Does anyone have any removal suggestions or tips? Heat is not an idea practice here because the fiberglass floor would melt.

Thanks in advance,
Dan
