Fitting Tech 1 Rear Spoiler Help Please

[MyOtherCarIsAnE30]

Hi, can anyone who has a tech 1 rear spoiler fitted or has knowledge about them give me some info about fitting one.

I currently have a standard little spoiler on my car, (not sure what its called but so many cars have it). I want to get a tech 1 and was wondering if it just fits into the same holes and how it is held on?

I have never removed my spoiler or put one on an e30 so not sure.

Thanks

Yes, the Tech 1 fits in the same holes as the standard. 6 bolts protrude from the spoiler into the boot and are tightened with the accompanying nuts from under the bootlid.
