(Phrases and Photographs by Scott Liggett) Anybody who has ever raced in a NHRA sanctioned occasion is aware of one of the primary guidelines is a correct battery down is critical to move tech in any class. Past the principles of varied racing sanctioning our bodies, protecting your automotive’s battery correctly is simply sensible for security’s sake. If you’re engaged on an 40 to 50 yr previous automotive, you recognize that the manufacturing facility battery tray is normally the very first thing to rust out.
As I prepped Mission Hay Hauler ’67 GMC for this yr’s Rocky Mountain Race Week, one of many few issues I wanted to do was take of the battery maintain down. Now, the truck’s authentic battery tray and maintain down bracket had been nonetheless in nice form and in tact. However, I’ve had a tech inform that was not ok for racing. Not desirous to tempt destiny once more, I made a decision to make one thing that may not increase eyebrows of monitor techs.
I’ve made a number of of those maintain down over time, so this was the quickest repair I needed to do to make the truck legally to run down the monitor. I ran down the road to the native Tractor Provide for a chunk of metal flat inventory, a 3 foot 5/16″ threaded rod, nuts, washers, and two wing nuts. The whole was proper round $10.00 for every thing. If you’re questioning why I selected 5/16 threaded rod, it’s as a result of the unique maintain down thread dimension and supplies a simple spot for one of many rods to be positioned. With a washers and nuts above the manufacturing facility threaded gap on the battery tray, one facet is down.
The opposite rod between the battery tray and the radiator help required a bit extra work. The very first thing to do is to find a strong location. On these GMC’s there are two layers of metal which might be filler panel and the vanguard of the internal fender. After some measuring, then drilling…..after I measured a second time, I put in the opposite threaded rod.
With the battery again in place, it’s time to take some extra measurements to make the maintain down plate.to go excessive of the battery. That is the place the metal flat inventory is available in. I’ve additionally down this utilizing aluminum flat inventory which might look a bit fancier with a little bit of sharpening.
The flat inventory solely wanted to be lower to size and two holes to be drilled. Even if you happen to don’t see your self as any form of fabricator, even a novice could make this. Simply measure twice earlier than drilling the holes.
I double checked the fitment earlier than going any farther. In case you might be questioning why, it’s as a result of I’ve not measured twice up to now.
Lastly, a pair coats of semi gloss black engine paint to make it fairly, I put in it for the final time checking this off my to do record.
Beneath, is an previous image of the maintain down I made years in the past for my ’70 Caprice. This one was made with aluminum flat inventory.
