Measurement request - manual trans owners step inside!
 

Evening folks-

I'm in the middle of gathering parts for a gmt400 5 speed conversion, and I've just found out that GM discontinued the shifter boot for my truck. I *believe* the boot they used on 99-06 trucks will interchange, but I don't have one handy to compare.

So, would some kind soul be willing to measure the overall base length / width of the shift boot, and also the spacing of the screws retaining trim ring on the boot.

Thanks in advance!

9" wide by 8-1/2".

Mine only has 4 screws, 1 in each corner under the rubber. There are some other holes that are larger, perhaps something left over from the molding process.

99 Silverado 1500, 5-speed, 4.3 V6

Well that's unfortunate! I just went out and checked the boot in my pickup, it's 6-3/4" square. Same 4 screws in the corners.

Back to the drawing board. S10Fan, thank you sir!

Have you already cut a hole in the floor?
The Kenworth T800 & T600 boots are 7-3/4" square. That's only 1" difference edge total or 1/2" on each edge when you split the difference.

No, not yet. That is an interesting thought!

Overall, I'm trying to stay as factory as possible, and was hoping to go by the pre-dimpled markings on the trans tunnel, but that may not be an option if I can't find a good boot. The one in my donor is shredded :whine:

If you install it carefully then it shouldn't be an issue.
You're not going to Pebble Beach with it...:lol::lol: You just want it to look decent. Don't we all. It wouldn't pass full concourse muster with a non-stock non original transmission but who really cares.
