Making flat bed need advice

[1985toyota]

hey for all you flat bed guys i was wondering how to mount my flat bed onto my frame i want it on there nice and tight and if i roll i want it to stay on there :yes: should i use the stock mounting points? i do not want to weld it on my frame i may want to take it off some time in the future, And what would be the best way to floor it? ive heard of ply wood and ive heard of very expensive diamond plating....im on a fairly cheap budjet i was thinking sheet metal? who knows
Thanks guys any tip building for my flat bed would help a TON

i used the 6 stock mounting points,just made brackets off the flatbed and bolted it on.main reason is to be able to move it to another truck...

for my bed i used 14 gage diamond plate. $45 /sheet

and 2 sticks (24') of 1.5" square tubing. $25

weighs in around 200 lbs with tool box.

i used 1.5 square for the frame,but used flat 16 guage for the floor.i also had the metal bent for the fenders,less weldind and grinding...
