How quick do you need these?
We are in the process of manufacturing a steel fabricated bellhousing to fit the T5 to the L series motor.
Yes, basically the same as that available with the T5 trans. from the '81-'83 Turbo ZX.but more readily available and steel so it will be safer and hopefully SFI rated.
