Bagging Question

[Bennydog]

I Did search but didnt find exactly what i needed to know so here goes. I have a 65 longbed that currently has 4 inch drop from Cpp... 2 inch spindles and 2 inch spring up front and 4 inch springs out back. I will only be running 15 inch wheels and dont want to lay frame but I WANT IT LOWER!!. I am not against a small c-notch in back but do not want to loose my bedwood or cut my wheelwells, and not cut away the aprons in front either. Not interested in raising the bed floor either, So is this possible? Has anyone bagged their truck leaving the stock Bed wood ect,,, Any help and info or pics on the matter would be appreciated! Here is a pic of how it sits now
