Found these on ebay. The seller has a few other's for g-bodys, but I think they'll only fit Montes/Malibus.

RK Carson,Thanks for the info.I purchased Q-Logic kickpanels from Crutchfield that I have not installed for my 87 ,then installed a 5 speed and with the new clutch pedal there in not enough footroom to use them.It looks like I need to go with door panel speakers. 82 Elco has a similiar great set up I saw on his member photos that other interested members may want to check out.In addition to the killer stereo setup he has,there are several nice things he has done to it that is worth a look.I contacted www.montecarlodepot.com and got a speedy reply.Their lower door panels fit 78-87 El Caminos.It is marked on the backside for the electric doorlock switch and remote mirror control or for $25 they will cut them out for you.The panels house two 6 1/2 in.speakers.Your info is good for anyone looking to add speakers to an El Camino that is limited in good places to mount speakers that are not in the way .I will be contacting them soon.Thanks
