Question about hidden bed strips

[floridasteve]

I purchased by bed sides from the vendor with polished angle strips, no holes, welded to the bed sides from the factory. Here is my question. If I went with the polished Hidden strips for the bed am I ok not to drill into the angle strips? I understand how they fasten in the strips and the angle are not set up to use the fasteners. I also see that hidden fastner angle strips are not an option.

So here is the dilema. Do I have to drill the holes in the sides and use a polished angle cover? Seems useless to have ordered the polished in the first place if so. Second, Am I ok to go with hidden and not attach the wood to the sides with fastners? I would just leave it under the strip in the groove and use the hidden everywhere else.

Thanks in advance for the anticipated responses and pics. I could not wait to get an answer from the distributer in the morning!
