i took out my bed in my 76 el camino because it was rusted out, i was wondering if ne one had ne tips how to make a template?

You can purchase the Bed floors. This place seels them http://www.ss396.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=396&Product_Code=RBF-39L&Category_Code=SHE-001 and I am pretty sure so does, Goodmark, The El Camino Store and EC Parts among others.

THe replacement Bed Floors are not just like Original. They are minus the Smuggler's Box and Lid. In other words they cover the entire bed. You get a left side and a right side.

Hope it helped. The probably will not say they fit the 76 but if you call them and ask you'll find they do work.
