Well I am a newbie and I am friends with greaser.I built this frame in the discussion.Thanks for all the criticism.The frame will still get front tube member in the motor mount area and there is also a bolt in style transmission crossmember that that is about 3 ft long and narrow that forms a small x member.The hole frame is .250 x 2.0 x 4.0.It is pie cut from firewall forward on the sides thet drops down to 3.0 tall for the crossmember.I have bagged many cars and trucks.Everybody does things different.The dually in the back ground is also my daily driver I bagged.The rear suspension I set up has never let me down in the past.The buddy I built this four is doing a 4 door 31 Murray body.Useing sedan doors for front and rear doors and then filling the back stock doors.I told him it is too long for me.Sitting next to my stock model a.Also here is the back frame portion on my 1953 ford I did.
