    A bell crank, or a cam.

    Why does no one make aluminum replacement body panels.

    I hope we've answered your question. ;)

    Why does no one make aluminum replacement body panels.

    Now I'm done. You can see my post #2 was "pregnant" with meaning! K

    Why does no one make aluminum replacement body panels.

    Total sidebar: they also used to make scale models of stamped parts to test the "draw" of the metal, since the characteristics can be scaled down (known as "similitude". You can do that more famously with wind tunnel testing as well). One time they made a bunch of 1/4 scale Chevrolet oil...

    Why does no one make aluminum replacement body panels.

    In addition to my Dad's 26 years as a die maker in Flint I have a little sheetmetal experience of my own. At one time I had design/release responsibility for the GMT900 pickup front of dash and underbody, pickup box, and G van underbody structure. I also worked on a low volume production/show...

    Why does no one make aluminum replacement body panels.

    Not to say it can't be done, if time and money are no object. This little car is one of six 1963 Pontiac Lemans coupes (there were also six wagons), created specifically for drag racing with a 421 cubic inch engine, special 4 speed transaxle, and aluminum front end sheet metal. It created...

    Why does no one make aluminum replacement body panels.

    Coming back to this: a person CAN run aluminum sheet through the existing steel dies, but as noted above the springback is different and so the fit will be different. My dad worked at Chevrolet Flint Manufacturing - Pressed Metal division (aka "Chevy in the Hole") and had to run some aluminum...

    Why does no one make aluminum replacement body panels.

    Because they would be expensive and difficult to make. K

    Vacuum Brake Booster

    There was a manual brake system and a power brake system available in 1979. Need to know a bit more detail about your truck, like series (10, 20 or 30), GVW or ideally the brake code (JB3, JB5 etc). K

    Pinion angle for lowered SWB Square?

    Hmm - This is from 13 years ago - https://www.motortrend.com/features/sucs-1046-keith-seymores-1974-chevy-chevelle/ And this one is from this spring: https://www.nmcadigital.com/blog/keith-seymore-is-committed-to-honing-his-skills-and-his-combo-for-multiple-drag-racing-classes/2148 K

    Custom Tail Lights or Not

    C'mon - use your imagination! Ok, ok. If you DO use the factory lights, make sure to run a ground wire from the bulb socket down to the frame. The original ground via star washers, which break the paint on the bracket and then rust. If you paint everything up nice you won't have a good...

    1973 Monte Carlo Very Rare Factory Sunroof - $6,500

    Yep. We had one in '73. Normally dad ordered all his vehicles but he was passing by Applegate Chevrolet in Flint and they had one sitting out. Maroon, no vinyl, rally wheels, black and gray herringbone weave interior with swivel buckets and the rally cluster. Bought it on the spot. Turns...

    Custom Tail Lights or Not

    I disagree. I always wanted to do an old El Camino bumper with the lights down there. I think the rear of the stepside fender with nothing blocking the view looks awesome. K

    Did K-10s have different brake options?

    All the same in terms of rotors and calipers. My guess is someone at US Mag didn't do their homework very well. K

    Pinion angle for lowered SWB Square?

    Yes - correct. No issues, so it's not something I checked or worried about. Intiuitively, it should be better, since lowering the truck (ie, raising the rear suspension up into the frame) lessens the angles on both ends of the shaft. It's probably more important for the working angles to be...

    Pinion angle for lowered SWB Square?

    First thing: the u joint working angles are with respect to each other (ie, shaft to pinion, or shaft to trans). They don't care what the relationship is to the vehicle, or the ground. Your truck could be upside down and the u joint working angles would be the same (assuming - of course - the...

    Factory Seats; Why do they suck?

    Because they have to fit everyone. One of the seat engineers complained to me one time: "imagine taking a pair of jeans and having everyone in the room try them on, and then tell you what they think". K

    '89 Burb V2500 JB7 Different Pad Options?

    One potential solution here is to be hard of hearing. Another, perhaps better solution, is to turn the radio up. K

    '89 Burb V2500 JB7 Different Pad Options?

    You don't. You have JD5 and 7300 gvw, which is specific to the diesel/hydraboost combination. K
