High Hump - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Captainfab** · 09-02-2018, 12:52 AM

I just ran across this while looking for something else. I did not realize that steel high humps were being reproduced. They must be fairly new. I see that complete firewalls are now available also.

Nice find.

I know there is a vendor working on doing a high hump and the firewall part. Not sure where they are in the process.

Are you taking about Mike Losh?

Clarification on the high hump...whats the need for it...?

**PGSigns** · 09-03-2018, 08:08 PM

Nope one of big the metal guys. I supplied them with a high hump and the fire wall piece. They planned to scan the pieces and see if they could start making them. They have the resources to do it.

**Captainfab** · 09-04-2018, 12:19 AM

The SM420, SM435, SM465 and most newer OEM and aftermarket 5 and 6 speed transmissions need the room.

Is it someone that will make them domestically?

I think they will be out of one of the Taiwanese plants. They are a big supplier of body parts and the resources to get stuff done.

**Captainfab** · 09-05-2018, 11:52 PM

The high hump cover I posted a link to is likely made by that supplier.

Interesting. Great find.

**62bagger** · 09-08-2018, 10:44 PM

I just received my trans cover today from classic parts and it is not the high hump. From the picture in classics site its hard to tell. I'll give them a call on Monday and see if the high cover is available.

Would you be able to post a pic of the hump you got?

**62bagger** · 09-09-2018, 08:10 PM

Here are a couple of pics of the trans cover. It seems well made just not tall enough.

**62bagger** · 09-09-2018, 10:17 PM

OK, I'm not a metal fabricator. But I was looking at what the PO had done to get the trans to clear (first Picture).There are some really good fabricators on this site and I was wondering if anyone has modified their low hump like this? It might be a bit of work but I thought it might work pretty well.

**Captainfab** · 09-10-2018, 12:03 AM

So it isn't a high hump as it appears in the pics......I stand corrected.

**62bagger** · 09-10-2018, 12:11 AM

the picture was not very detailed. Since I have not found another high hump I was thinking of modifying mine as pictured.

A friend of mine has a 68 Gmc with factory th400. If I remember correctly it has a high hump. Did gm make the high hump a standard for all transmissions in the 67-72 years?

Not sure if you are interested, but I have a two piece high hump listed in the classified section ( CA Garage Sale ) Not as nice as a new one, but might be easier than modifying a low hump.
Good luck with the project,
Tom

**Captainfab** · 09-10-2018, 11:47 PM

No, the '67-'72's had both low and high hump trans covers.

I found this tonight on ebay when searching for a high hump cover...Interesting...not a bad price $150 shipped.

**Captainfab** · 04-05-2019, 11:28 PM

I see that they also have one with no holes, which is nice. However the one review on this cover is not good.

roll_the_dice · 04-05-2019, 11:59 PM

I just saw that review. Looks like only part of the 2 piece high hump...wonder why they don't make the upper portion?

**Captainfab** · 04-06-2019, 11:37 PM

The forward section would be difficult and quite expensive to reproduce. I doubt that people would pay the kind of money a quality steel reproduction would cost when the Slosh Tubz fiberglass version is available.
