Couple questions about roll cage, frame and flywheel deflector

[Boostedballs]

I have the 2009 rulebook but I need some clarification on a couple things.

I'm building a 1975 Monza for gas coupe C class, I think.

Here's my plan for the cage:
1 5/8 .120 DOM for the hoop that goes over my head and the one that goes across the top of the windshield.
1 5/8 .120 HREW for the rest of the roll cage inside the car.
2x2 .125 square tubing for the frame/cage under the car.

I want to use 6x6x.250" flanges to sandwich body sheet metal and connect the upper round tubing to the lower square tubing.

I don't have a lot of room under the car for a flywheel shield. So I am hoping to box over the bellhousing hump INSIDE the car with .250" plate. This will be welded to the cage and extend under the pedals and extend aft to the point where the factory hand brake lever was. Will this suffice?

If your running a stick shift you need a bell housing. A Lakewood or McCleod fits in place of a stock one so why not use it? Normally the 1/4" plate rule was for engine that one was not available. If you are using a small bellhousing like a Quartermaster I could see your point. I you have the book look up Steve Davies # and ask him........Good Luck

As JD says use what's out there safety wise if you can. If you must build one the rule book says 360 degrees AND provide retention, so just sheilding the floor won't cut it IMO.

Good Luck

The Monza came with a special bellhousing, where the clutch fork is mounted way low because there just isn't room for it on the side.

Maybe I'll have to hack up the transmission tunnel to make the aftermarket stuff work???

Lakewood makes a belhousing that takes the lower slave cylinder (I have one) but I don't know if it clears the stock monza firewall.
We've cut the bottom of the belhousing and welded in a flat plate for ground clearance. This requires an aftermarket small dia. clutch assy though.

Good Luck.

The Lakewood SFI bell housing with block plate and bolts that Fit the 1967 and prior Chevy II's (Nova's) should fit the Monza as well.

McCleod also makes a nice hyd throwout assem so you have no linkage or external mounted slave cylinders.

McLeod makes a wonderful clutch assembly, too.  Have one myself.  But I'm not crazy about hydraulic throw-out bearings when mechanical linkage or even slave cylinders can be used.  The latter are sure a lot easier to repair on the spot.
