It’s Only Nuts ’N’ Bolts
Painted Door Installation— A Less-Stressful Way

ust a short while or two back in the Sept. ’25 issue, we endeavored to illustrate the installation and easier break-in of slightly slimmer (PN 60-0485-72) door weatherstrips from Steele Rubber Products. That was for our ongoing 1955 second-series Chevy build, and as always those particular weatherstrips truly made the easier break-in difference.

If you happened to catch the aforementioned story before ordering Brand X online door weatherstrips for your own Task Force or Blue Chip truck project, we’re pleased if we’ve saved you frustration. Even so, our own work is still not quite finished here.

We’ve talked about the weatherstrips, but it seems to yours truly that the nuts ’n’ bolts of the job might be worth a mention as well. At this stage of our subject truck’s build, panels are painted. Yes, for the most part, they’re in living color, and hopefully for keeps.

Even this late in my own painterly game, I still enjoy painting. On the flipside, I don’t enjoy repainting! What comes next here will count. This is where preventative steps taken earlier are about to finally pay off.

When we were focused more on weatherstrip installation and break-in, we might’ve mentioned a little trick for realigning doors, as we liked ’em once before. Several months back, at the end of a marathon dry-fit exercise, we called our fitment good. Regaining those gaps would be difficult from scratch, especially now with doors painted and new weatherstrips already installed.

The little panel realignment trick is hardly anyone’s secret. Others may’ve done it routinely for eons, but honestly, I didn’t know ’til I witnessed it in Riverside, California, at the original Ed Martin Garage. There, it wasn’t so much about panel gap perfection. It was merely a means of relocating a hood. It was how they’d put it back exactly as it was when the customer brought it in. Here at our own shop, we’ve adopted the method for hoods, doors, and occasional decklids as well.

So, as we ease into the nuts ’n’ bolts segment of our story, I might as well confess: I’m what you might call a hardware hoarder, or a fastener amasser if you prefer. In short, I just like having my nuts ’n’ bolts all gathered. For those occasions when there’s truly a difference, I’ll restore the original stuff.

While most Task Force and Blue Chip trucks we see use hex-head body bolts to secure door hinges to the cowl, our Oakland-assembled project ’55 came with smoother fasteners. Hopelessly unable to resist, I went ahead and restored them. Back when that story ran, I received a surprise from reader, Ralph Hernandez, who knew something I did not. As it turns out, the same smoother door hinge bolts I’d labored to restore are now reproduced. In fact, they’re quite affordable through Auto Metal Direct (AMD), so let’s have a look at those also as we go.

Granted, you might say “it’s only nuts ’n’ bolts.” With body parts in living color, however, final assembly is far from stress-free. This might likely require every ounce of finesse we can muster. With that said, here we go—again.

1. Here for example, in this old wrecking yard, we see the usual hinge-to-cowl hex-head body bolts. This is how most Task Force and Blue Chip trucks tend to be.

2. Back at the shop, we’ve replaced our worn-out door hinges. The smooth-style hinge-to-cowl bolts, however, are 1955 originals, and we’ve got some time invested.

3. Thanks again to Ralph Hernandez, we’re now aware of these beautiful reproduction bolts from AMD. When our project goes back together for keeps, these will be the bolts we’ll use.

4. Earlier we alluded to a little panel realignment trick. Here in dry-fit stages, we’re satisfied with our gaps. Semi-discrete 1/8-inch holes will help us regain our gaps later on.

5. We’ll do the same thing here, with two 1/8-inch holes through door hinges, and the underlying sheetmetal of our doors’ hinge pockets.

6. Now skipping to final assembly, let’s expect the usual paint buildup in threads. An oily tap will clean them out, but a slotted hex-head bolt will do a cleaner job of it.

7. Fashioned from 1/8-inch drill bits, our realignment tools are dual-purpose. Here for example, they’re the just-right fit for cleaning out this bit of paint buildup.

8. Here, as we tighten things up, they’re dead-on precise for relocating door hinges to cowl.

9. For lower hinges, the steps are the same, except for the lowermost bolt. Here we’ve restored some extra-toothy OE lock washers. Restorer-types might notice this.

10. With hinges now accurately reaffixed to the cowl, it’s time to hang a pair of doors. To make that a little easier, let’s first get this truck sitting level with the concrete floor.

11. As it came years ago from Harbor Freight, this hydraulic motorcycle jack sees occasional motorcycle use, but here at this shop its primary purpose is hanging doors.

12. For the deeper upper pockets, we could’ve/should’ve made longer realignment tools. We do have longer 1/8-inch bits, but in a pinch an icepick works just about as well.

13. If the semi-discrete holes bother you, the same job might be possible through the deep recesses of the hinges. For best accuracy, we prefer the wider spread between holes.

14-15. Should additional weight from glass and such affect our gaps later we’ll fine-tune as necessary then. Here we have gaps—just as we liked them once before.
