So I just came up on a 88 ef sedan its a dx model with ac and ps stock everything just have a couple of questions ……

It doesn't have a radio or radio harness

Would a 91 si sway bar fit when I throw on the si lcas ??

 

I believe the radio harness is there. You will just need to look for it inside the console.

Rear sway bar requires the rear sway brackets. The LCAs are the easy part.
There aren't threaded holes for the brackets to mount into.
Easy fix is to just get an aftermarket bar.
To mount the stock bar, you will need to cut holes through the floor of your trunk so that you can put nuts on the backs of bolts.... not required if you use an aftermarket bar.

 

Alright thanks bro cuz I just bought this for 1300 clean title and no radio checked and I didn't see a harness hanging around in there center consolet but ill pop the center console off and see what I could do ……

Alright well I got all of the si rear sway bar thanks for the info
