So I made the decision not to go with the full cage and will go with a roll-bar, rear down tubes, and engine compatrment tubes. What I will leave out are (primarily) the bars that run from the roll-bar forward along the top of the window and down the a-pillar. My reasoning is based on the amount of space taken up along the a-pillar and foot well areas; I'm just not willing to sacrifice the amount of space necessary.
So basically I spent hours mocking up a couple of bars I'm not going to use!
Like I said, I am going to run the bars from the firewall forward to the frame rails for a couple of reasons:
1) with all the cowl/firewall work I've done the bars will add some rigidity and eliminate any chance of cowl shake.
2) the fenders need mounting points along their length and I'll be able to mount tabs from the bars to the fender
3) an added benefit (I'm hoping) will be the ability to mount some fabbed up inner fenders to help clean up the engine compartment
Here are a couple pix of the roll bar mocked into place:
To get the roll bar in place I cut a hole in the floor at the base of each leg, dropped the bar through the holes, lifted the bar vertically into position, blocked it from underneath, then strpped it so the legs are perfectly vertical. I'll cut the legs to length, trim them to fit the floor, then weld them and the base plates to the floor.
I'll get moving on the front bars (including pix) next time.
