The entire Holley swap system (brackets, mounts, oil pans, accessory drives, etc.) is designed to decrease your total swap installation effort and cost, while increasing the engineered quality of your vehicle and compatibility of these components with other popular aftermarket components. The experts at Hooker BlackHeart have taken away the guesswork of where to position your engine swap and we've followed up on our popular GM G-Body LS line with a new version that allows you to choose LS or LT engines by utilizing 4th Gen F-Body clamshell engine mounts. To complete the engine mounting be sure to follow these steps: 1). Choose the proper clamshell for your engine: Gen III/IV (LS) - 71221018HKR Gen V (LT) - 71221019HKR 2). Add the thru bolt kit: GM LS/LT/Gen III Hemi - 71223015HKR 3). Choose the polyurethane insert in the color you prefer: Black - 71221016HKR Red - 71221017HKR For the transmission, this kit is designed to be used with the same G-Body transmission crossmember already in production (12644HKR-1) for a trouble-free installation and optimized driveline angles. This system is compatible with almost any popular GM transmission, even modern 6-speed, 8-speed, and 10-speed applications. An adapter kit may be necessary for applications that were NOT equipped with a 200-4R transmission from the factory - Part # 12647HKR. 12644HKR-1 - Transmission Crossmember (no additional adapter needed for TH400/200R4/T-56/Magnum) 12655HKR - 4L60/65/70/75 Transmission Adapter - use with 12644HKR-1 12656HKR - 4L80/85 Transmission Adapter - use with 12644HKR-1 BHS5181 - 10L80/10L90 Car Transmission Adapter - must be used with both BHS5182 and 12644HKR-1 BHS5182 - 6L80/90, 8L45/80/90, 10L80/90 Transmission Adapter - use with 12644HKR-1 BHS5183 - Tremec TKX 5-Speed Transmission Adapter - use with 12644HKR-1 *For installing a 10-speed GM car transmission, both BHS5181 and BHS5182 will be used together to achieve the proper spacing and alignment.

Size: Standard (Mid Loft), Number of Items: 1
Finally! After so much wasted money on sooooo many pillows, I come across this beauty! This pillow is amazing! I got the medium one, and it’s so perfect. Soft, yet supportive. I’m still surprised at how much I love it!

LOVE IT !
Size: Queen (Mid Loft), Number of Items: 1
I love this pillow. It is just right, firm enough yet soft. My head sinks in and is very comfortable. When I lift my head, the pillow bounces right back into shape. If it lasts, I will buy my family each a pillow as it is wonderful. I woke up with zero neck pain as I typically did when using a standard foam pillow. There is a very light scent yet when I covered the pillow with a protector casing and then a cotton case, there was zero scent. I highly recommend. Especially when compared to the comfort of a very expensive latex pillow my husband uses.

Dream pillow
I’ve been using latex pillows for over 30 years, and I can’t find them in local stores anymore. I’ve been needing to replace my pillow and finally decided to try this one. There are so many options on Amazon that it’s overwhelming. But this standard low loft pillow ended up being PERFECT. It feels amazing and just like the pillows I’ve been using since childhood. It is soft but cradles my head and neck perfectly. For me, it’s like sleeping on a gentle cloud. Very happy with my purchase. (Yes, it does have a slight latex odor. That is normal due to the material. It’s not very strong and it doesn’t bother me).

Great latex pillow
Size: Queen (Mid Loft), Number of Items: 1
This review is for the biamktp queen pillow. Medium firmness. Finally a latex pillow worth keeping. After trying many other latex pillows I'm finally sleeping comfortably. This pillow is soft, yet firm enough to give your head support. I'm not having any neck or shoulder pain when I wake up. I'm sleep on my side about 95% of the time. 5% on my back. I've been sleeping with this pillow for about 10 days and still am happy with it. It was delivered on time, absolutely no odor and it has a removable cover. I highly recommend it.
