lol, i had recaros in mine, and a comfy cortina rear seat sqeezed in, gave a bit more room for speakers in the back shelf with the seats being taller
mine was a mobile disco hahahahhaahh, 5 speed box, that engine with the twin 45 webbers on and it was a 1600cc pinto with a rare 1300cc head with big valves (near the size of the 2ltr ones) on it, this bumped up the compression to 11:1, a piper rally cam allowed it to revved happily to 9500RPM sounded nice, but it became to much work to keep on the road, and shattered 2 RS2000 diffs, then i was offered the silvia.
