Fram plugs?
 

I feel like this thread fits in both tech and general cbrf2 forum. so here goes.

I've removed the back end of my subframe, and im wondering if anyone know of any plugs i could use in the frame.

If your talking about the tubes and your looking for a simple temporary fix, you may try the hardaware store. Lowe's has a section near the bolt section that has furniture parts. They have some rubber plugs that go in the legs of patio furniture and the metal chair legs or table legs. May find something you can use there.

Ah, really good idea. Actually my girlfriend works at a furniture shop, maybe they have something.

We don't have Lowe in Norway :)
