Rear torsion bar hole

[draab29]

I was just looking through an RSR conversion/backdating thread and saw a mention of 'half-moon' rear torsion bar holes on later model cars. What year did they change from the full hole to the half-moon? I have and '84 TLC and would take a look myself, but don't have time to remove the rocker panel today. Thanks

the year change was MY1987 when the switch was made from the 915 to the G50 transmission.

I think it's because they had to move the Torsion tubes out a little to fit the G50. The MY87+ cars looks funny when they rockers are removed. You can get away with it on a earlier car and it looks cool, but the later cars...it's evident they didn't expect it to be left off. You can actually pull the fender out a little to remove the spring plate covers.

Funny thing about the Carerras...I see where the weight comes from. The 89 model I just helped a friend with had an extra "support" for the cat converter.

Do they make special steel flares for backdating these years?

Actually the change happened in '86 in preparation for the G50 transmission. '86 Carreras have the larger G50 TB openings.
