Howdy Y'all,
I'm new to this site, but an old hand at 73-87, 88-91 GM trucks. I've owned more of them then I can remember.
My current project is a 1988 Chevy Crew Cab Dually C-30 that I've been tinkering with for a few years.
So far I've done DJM upper and lower control arms, DJM rear spring hangers, 89-91 front clip, B&W turn over ball gooseneck, 10K receiver hitch with 7 pin trailer connector, trailer special rear bumper, 454 stroked to a 496, RV cam, ported and polished heads w/ 2.19-1.88 S/S valves, coated headers, billet distributor, SBC serpentine belt drive conversion,Turbo 400, rear view camera, full LED conversion.
I'm currently working on taking the Edelbrock MPFI off and installing a Marine MPFI system from a Mercruiser 454.

Future plans call for a Cowl hood and a set of 22" Alcoa's



I do have a question?
After installing the DJM control arms, I can't get the alignment set, I've put all the shim in I could fit and I'm still -2 degrees out. I've rechecked the lowers for proper seating in the frame and they are located on the pins properly. Is this common?

First off :welcome: Secondly get some pictures of that beast up on here asap! As far as the DJM arms are concerned, I have read that sometimes it is nearly impossible to get the negative camber all the way out, as this is a problem for almost any type of lowered set up. Some other guys on here that have more experiance will chime in soon and help ya out.

Welcome. Do you own any 442's?
I've owned an 1985 and 1987 442 ( some say they don't count but.....)
I currently own a 1983 Hurst/Olds and a 1984 Hurst/Olds along with my 2006 GTO.

Thanks..... The only pic I have at the moment is the truck setting in the garage and it's not a very good shot. As soon as I get this MPFI figured out and running, I'll pull it out for a decent picture.

As for the DJM, I only went with the 3" drop A-arm, keeping the original springs. I really thought that would keep it alignable??


A friend of mine has an 1986 C/C Dually GMC 4X4 454/400 that is in pretty nice shape. I'm hoping to pick it up from him soon as he wants to sell it, but " keep it in the family ". It's all stock except a 90 gallon aux fuel tank in the bed, 89-91 front end and power mirrors with a " 80's Western Hauler " style custom paint/stripe.
It's just begging for a 6" lift and some 35's.
