Convertible bolt size/thread
 

I'm looking for all the bolts needed to attach the vert to the chassis (frame and motors). The guy I bought my 7 from completely removed the top. The guy I bought my replacement from didn't give them to me, he threw them away. I'm desperately trying to find them or at least figure out the dimensions of the thread and size of the bolts so I can buy them at lowes or something. Does anyone know what the dimensions are? I've already looked through the manuals linked to the forum. Most of the links here are too old to pull up.
