    I needed to get the radiator forward further, so I could add a 90 molded hose to
    the barb near the steering box, so I cut some more off the front of the bottom
    radiator mount from the Firebird, and drilled 6 holes into the stock mount to get
    a good spread of support. I used some self tapping screws from a parted out '98
    Camaro.;)

    You might notice that I had to slide the radiator a tad toward the passenger side
    of the car, that was because after trial fitting the fan assembly, it hit the IROC
    steering box at the 4th Gen lean. Now it clears by about a 1/2 inch.

    Then I took the Firebird top plastic piece and added a 1/8 inch thick piece of
    steel to the underside, drilled the passenger hole over a bit to clear the stock
    2nd gen bolts and added 3/8 stand offs I got from Ace Hardware.

    Then I drilled holes through the stock upper brace, leaving the original tapped
    holes intact (for whatever reason) :

    Now I should be able to use all the stock 4th Gen Firebird hoses and the stock
    transmission cooler lines. The plan is to add some aluminum to each side of
    the radiator to direct air through it, and not around. I will see if the plastic
    piece from the Firebird might fit. Was getting late.

    Still trying to come up with a good mount for the top of the radiator. I moved
    the top back a little more, I'm pretty much dead-on with the 4th Gen lean. I'd
    come up with a cardboard mockup for a sheetmetal top that would inclose the
    front area near the latch, as well as attach the stock 4th gen plastic shown
    in the pictures - still working on it. I used the battery cables from the Firebird
    which includes the Alt power lead, ground to engine, and chassis ground. I also
    made a simple bracket to mount the power steering tank.

    Followed through with the mockup using just the upper plastic support from the '94
    Firebird, but that put the cap in contact with the hood spider.

    Not wanting to cut the hood, I decided to lean the radiator so the cap is level to
    the ground, like in the Firebird. This required an upper mount to be made. I made
    a mockup out of cardboard to get the shape, and painted it black to sell the wife
    on the concept.

    After I got the OK, work began on the sheet metal version. I bought a piece of 18
    gauge steel locally, and a sheet metal bender from Harbor Freight. The max gauge of
    the bender is 18, so it taxed its abilities. After cutting the pattern out with a
    dremel cut off wheel, I setup the steel on the bender. Small bends done in a simple
    vice and really narrow bends done with pieces of thick steel, a C-clamp and hammer.

    Checking the bends against my template pulled from the mocked up cardboard.

    Second bend done.

    Next was to trial fit the steel in the car and do more cutting.

    Closing the hood the first time got me aware I needed 3 more bends, this also put
    the leading edge of the material down against the bumper support to put the steel
    under spring tension : holding the radiator down.

    The radiator sits on the modified Firebird lower mount bolted to the stock mount.

    Radiator cap is level to the car and the upper steel mount.

    Cleaned it all up and painted it with Semi-Flat Krylon and bolted it up. All the
    stock hoses fit, just the upper hose on the drivers side had to be shortened 1 inch
    because I shifted the radiator to the pass side so the fans clear the steering box.

    I installed the Shiftworks shifter conversion kit too, it requires you remove the
    shifter from the car and drill out the rivots to install their new detent plate.
    It also includes the pieces required to make the lock linkage to function.

    Console back in (yes thats a 3rd Gen Firebird steering wheel).

    Installed the Moog upper ball joints into the PTFB control arms and on the car.

    Clears the hose and the engine now, added benefit is the 3rd Gen wheel has more
    room with the outer edge (rubbed with the stock arm).

    x2 very nice work on the radiator cover. be sure to block the area off between the sides of the radiator and the core support. This will allow the air to go through and not around the radiator.
