Does lokar make a speed manual shifter?
Why you asking hard questions? Lol. Actually I don't know if they even make manual shifters. I may have spoken to soon. On the other hand, I assumed all manual trans had swithches built-in? I guess I've gotten old and have forgotten how ancient this period correct stuff has become. In that case, an LS and NV4500 is in order.

Yeah the LS option is a few years down the road. Have a kid who's going to be looking at colleges this year and they're going into the medical field. So...... lol
But the truck was originally a 250 I6 with a 3 on the tree so the reverse light switch is at the base of the steering column. So I'll need to customize the backup light function. Have some decent weather coming in tomorrow and hoping to get the new switch mocked up and fitted.

If you already cut the floor, I’d swap to a 4spd and call it a day…

Rick, I'm not following on how the push-pull switch would not activate in both park and reverse, UNLESS it was mounted 90 degrees to the shifter so the shift arm only activated it while in reverse.

Initially, because of space constraints, my mind went to the switch being on the park end, rather than on the side, for a push-pull, because they do take up more room than a microswitch. Thus the conclusion it would activate in both park and reverse.

A person could get around the "on in park and reverse" by using two switches. The second would be a normally closed switch and would open when you went to park the position [circuit]. The reverse would be a normally-open switch and would be closed in both park and reverse.

More of a pain to deal with (two switches), but still pretty simple, electrically speaking.

The switch I pictured in post 14 is only on when there is tension pulling on the spring. So you mount it where ever, but close to the transmission you put a pull wire on the spring, attached to the reverse shift lever. Now adjust your pull wire length so the switch is pulled on only when the reverse shift lever is in reverse position.When you move to neutral,1st,2nd,3rd,anywhere but reverse there would be no tension on your pull wire. And why are we talking about a park position on a 3 speed manual transmission?

I'm thinking of the standard shift moves: 1st. 2nd, 3rd, neutral, reverse, then park. All in line.

That aside, attaching it to the revers shift LINKAGE would seem to make sense, aside that I don't know the movements of said linkage.

Said another way, I had not focused on the linkage, versus the shifter.

ALL that aside, it just dawned on me, another option would be a magnetic switch.

A 3 speed manual does not shift in a straight line there are 2 shift levers on the transmission 1 for reverse and 1st. Another for 2nd and 3rd. I'm talking about using a pull wire on the 1st reverse lever to pull a pull wire when you go into reverse.

I've been doing some research but nobody has really discussed this here, so here it goes...

My 83 stepside was originally a 4.1 and a 3 speed Saginaw on the tree and has been moved to a floor shift. Yes I know the backup switch is on the column, but need an option to move the functionality to the floor shifter. What options are those of you who have done this using? Looked at some spring pull switches for street bikes etc as a possibility. Can't use a toggle switch because my state inspection requires it to be an automated process for the backup/reverse lights to turn off and turn on. Basically looking for something that doesn't need a lot of fabrication work to make it happen. Trying to be as minimally invasive as I can, aka just being lazy lol.

Thanks!
You've got to be kidding me? Back Up lights are REQUIRED for safety inspection??? Ohh wait, you're in woke azz MA so I'm not surprised really. Damn, do they require a back up alarm too? MoneBack, MoneBack Trash truck backing up Beeep Beeep Beeep !!!

I'm out, because I used a toggle switch.

The thing I liked about the toggle is I could flip the lights on for doing stuff around back in the dark, like hooking up the trailer.

Besides, I love them on a toggle switch. When someone is riding your azz and you get to the next light, you can turn on the back up lights with the toggle and rev your engine up. :lol: Watch them back up a bit then.

Yeah, but in a red stronghold in this blue state so it's not all that bad .
And yeah, that would definitely be fun to see the look on their faces. Almost as fun as droppimg 2 gears and dumping the clutch in my 99 LS1 6 spd powered Z28 on 495 .
