  • Our patent-pending tab-and-slot version of the 10L90 Swap Block Transmission Mock Up Block provides accurate transmission mounting and yoke positions.
  • This unique design is lightweight and comes disassembled for ease of shipping and storage.
  • One tool accomplishes accurate placement of a TH400 transmission found in GM cars and trucks from 1964-1990.
  • This mock up Transmission has a rear mount plate designed around the short tail TH400, but if a long tail is needed, you can bolt a tail shaft to the rearmost upright plate.
  • Easily positioned by hand, there is no need to bench-press a heavy transmission into place for fitment and fabrication of Crossmember, etc.
  • Save time and money and work more safely.
  • Durable steel construction resists heat from welding, so unlike foam blocks, custom crossmembers can be fabricated close to the block.
The TH400 transmission is the heavy-duty version of a TH350. The TH400 was electronically controlled, which required a kickdown switch by the carb or gas pedal to tell the transmission when to kick down a gear. They are still being produced and used in heavy duty GM and military vehicles. Here’s a list from Gearstar.com of all the cars that used the TH400 transmission:

1965-1967, 327 V8 (Rambler/AMC)
1968-1971, 350 V8 (Buick)
1969-1972, 225 V6 (Buick)
1972-1975, 232 I6 (AMC)
1975-1979, 258 I6 (AMC)
1972-1979, 304 V8 (AMC)

Finally, a pair of pillows that look good on the bed and feel good on the neck.
As much as I like the comfort and support of a cervical neck pillow, they usually have a strange ufo-type look and are usually quite small. It's fine for use, but they are not a great look on the bed. I wanted something more welcoming and full-looking with the support of a c-pillow. This set actually met my hopes and needs. I love how the pillow has two strengths - firmer on one side, softer on the other. That makes it easy to find the best fit for your own neck shape and support needs. The pillows are large enough that side-by-side on a queen sized bed they look welcoming and like they could probably even have matching cases put on them instead of requiring specialty industrial-looking pillow cases like many do. Having proper neck support has reduced headaches and neck tension and allows for better sleep!

Perfect if you're in the right position, not so perfect otherwise
I've been using this for about a week and I like it, but with some caveats. It is shaped so you can only sleep in 2 positions and you can't really move in bed. As long as you are in the correct position, it is really comfortable and provides the best support you can ask for. The problem is if you move around in bed, it turns into a hinderance. With normal pillows, they more or less move with you and are comfortable as you move. This is very specifically great in a single position, but terrible in any other position. If you are able to keep still, this is the perfect pillow for you. If you are like me and roll around too much, its more of a problem for sleeping than a help. I am going to move it over to my couch for napping with, and I think it'll work out far better since the couch isn't really big enough to roll around.

Great quality
Size: Twin, Color: White
This mattress pad is just thick enough without being overly bulky which tends to bunch up after washing. It is super soft and fits twin bed perfectly with just enough padding to add comfort. For a waterproof cover this one is superior to others I've had.

I’m buying more!
Size: Twin, Color: White
The quality of this product is amazing! It looks fantastic, super fluffy and comfortable, keeps accidents from getting onto mattress. It works so well! And is so worth the cost, I’m buying more for the rest of the beds in our house.

Fits great and very comfortable
Size: Queen, Color: White
I purchased because my cat is older and I need something waterproof. It fit my queen bed and my deeper mattress that usually needs extra deep mattresses. It looks nice and went on the bed easily. I have not had her test its waterproof feather yet. I am relieved I do not need to worry or put pee pads down for her. I reas some people find it hot and hear a squeaky sound. I have not experienced either. The padding is a nice addition. I was surprised by the soft padding feature as I was not looking for it. The price was great. I did not want to spend a lot of money for something that did not need forever given my cat is older with kidney problems now. I will not remove it even if it is not needed anymore because I like the cushion. I have purchased the Bedsure brand for other items and always been pleased with their price and quality. I recommend this product
