i transplanted an entire car, into entire other chassis. everything. all of it. from the interior, to the suspension, the engine, to the gas tank. i stripped it down to the chassis, and then i stripped the other car down to the chassis, and then swapped everything. all of it. sub frames. brake lines. everything. all of it.
i dont know if i would do it again, but im happy i did it.
the white chassis was borderline in terms of safely jacking it up it was so rusty. I had to weld bars under it last year just to change wheels it was such a mess. the blue chassis is more or less rust free.
