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.

Best money spent on a safe puppy chew toy
Size: X-Small, Size: X-Small
One of the best chew toys you can buy for your puppy! This kept him occupied for quite a while and it is one of his favorites.

Had a 6mo. old teething (English Bulldog) & this has entertained her for 9 mo.!
Size: Medium, Size: Medium
A chew toy lasting over 6 mo. is generally very good, for this breed & this brand! I kept it in her cage at night, so she wouldn't get board & start chewing on her paws. BC I felt it was a safe toy to use in this manner. "It was safe for my teething Bulldog." "Much, much better than other chew toys from this brand!" Others such as the Orange Pretzel they absolutely love! However, they have always splintered into very sharp edges of plastic, which cause the dogs mouth's to bleed (pokes their gums) & then NEED THROWN AWAY! This Key Chain Chew Toy was "really good" compared to other Nylabone brand chew toys, I have purchased! My girls mouth did not bleed from chewing on it:) "So, I am very pleased with this teething ring!" & would buy it again! Notice how the plastic splinters on the ends? Once the toy gets to his point I feel it is definitely time to be replaced! I would recommend this chew toy for a teething med. sized dog! The one I purchased was fairly large. & stayed together safely:) This is the only Nylabone Chew Toy I would ever, leave in a crate at night, thus far! Good Job Nylabone!

My dogs love their "keys".
Size: X-Small
My dog loves this. The only negative is that he does chew through it and I have to pick up the pieces or hope that he's not eating it.

Not long lasting for a chewer!
Size: Medium
These are massive! I have a golden retriever puppy and she chewed through the yellow ring very quickly. They keys are much more durable.
