i have picked up some 260 bits and have trawled the next ( and most of this forum) looking for the differences and these are my myths in addition to the what is already out there eg points abouts, trims, seats, bumpers, engine
i'm mostly interested in body/suspension only
the question concerns aussie spec '77 260, which i think comprises some bits from US 280, but with an L26 ( not sure on that one)
so, get your hot chocolate and ready to go
1. the door hinge holes on the A pillar base are round, whereas on 240 (71), they are oval (for adjustment). otherwise identical (true/false)
2. the tunnel is much wider, but the base porfile at the firewall and tunnel joins (about 30 cm from the tool boxes) are identical
3. seat belt mounts are different locations ( i'm not sure cause my car came with drivers belt diffetent to passenger) and some suspect looking fittings. pretty sure that there's mount in the inner sill. ithink that 71 was the year before retractable belts
4. the pattern for the stamping on the boot floor are different
5. different fuel filler pipe ( rubber vs metal)
6. one more hole in the boot pipe for some vent pipe on the 260
7. different mount for rear bumper, but that's just the bracket on the end of the channel
8. higher rear shock tower with additional reinforcing at top and on the innder panel on th 260 , but the inner wheel arch identical
9. diff door latch ( on body)
10. different size/profile/slope to the door jamb (i've eyballed and can't see any difference), so it seems to me that if you swap the latch, you can physically put a 260 door ion a 240, even if the door frame and internals are different)
that's all for now, i can post for any specifics
... like i sadi, one for the guns
