Hey guys.This is my first post.I'm looking at a 69 Biscayne 4 dr 427/390 turbo 400.I'm trying to figure out if it is real.The motor was rebuilt and I found an engine tie down in the trunk.Did these only come on BB cars?Are there any other things to look for.Does anyone know how many 69 4 dr BB cars were built?The control arms on the 12 bolt are huge.Were they the same on a SB car?Was the driveshaft or fuel lines bigger then on a SB car?Does anyone know where the build sheet would be?
Thanks
