- Fits Years: 77-90
- Fits Transmissions: TH400 Short Tail, 2004R, 700R4 with B-Body tailshaft Mount
- For Classic B-Body builders, we've designed a direct bolt-in transmission crossmember to accommodate both a 2004R or TH400 short tail transmissions, as well as a 700R4 with the tailshaft transmission mount. One crossmember, both transmissions!
- We accommodate both by using a second set of mounting holes on the crossmember which allows you to position the crossmember in two different locations while still using the factory crossmember mounting locations.
- No drilling, cutting, grinding, or welding is required.
- When considering the popular 700R4 or 4L65E, there are two basic transmission mount locations. One version utilizes a transmission mount directly behind the transmission pan on the transmission case. With the other version the transmission mount is located further forward and bolts to the tailshaft housing. It is crucial that you properly determine which mount location your 700R4 / 4L65E utilizes. The RCB3-400 is designed to accommodate the longer tailshaft mount. If you have the shorter case mount transmission, you will need to purchase our RCB3-700 crossmember.
- We recommend a polyurethane transmission mount. The GMTM is sold separately.

Powerful Superfood Supplement – Start Slow to Avoid GI Upset
These 500mg organic chlorella tablets are a great way to add a nutrient-dense superfood to your daily routine. They’re packed with vitamins, minerals, chlorophyll, and antioxidants, and I definitely noticed a gentle boost in energy and overall wellness after consistent use. The tablets are easy to swallow and made with high-quality, clean ingredients.
That said, it’s important to ease into the dosage—especially if you’re new to chlorella. I experienced some mild gastrointestinal side effects (like bloating and gas) in the beginning, but once I gradually increased my intake over a few days, those symptoms went away. Starting with a lower dose and giving your body time to adjust really helps. Overall, this is a great natural supplement, just be mindful to start slow and stay hydrated!

Take before PM Sleep - Cleans-Out Cell's TOXIC Heavy-Metal contents, promotes Sleep.
GREEN Chlorella (along with BLUE-GREEN Spirulina) can replace ALL your other Supplements at a Fraction of the Cost. Chlorella is recommended just before going to PM Sleep, as it's Main Function is to CLEAN OUT all the Heavy Metal TOXIN's in your body's 38 Trilllion Cells, overnight, plus Promotes Deep REM Sleep, during which all this CLEAN-OUT happens, particularly in your BRAIN. When you wake up, you will feel Refreshed, like you just had a Good Night's Sleep, but without the Bad Side Effects of Sleeping Pills. Combine this by taking BLUE-GREEN Spirulina, soon as you Wake Up in the AM, for Breakfast, then repeat for Lunch, and Dinner too, which is like ROOM SERVICE for FOOD. All you have to do is Eat 6 Tables of It per meal. Did you know BLUE-GREEN Spirulina has 1000x more Vitamins, Minerals, and other Plant Based Nutrients, that the Human Body NEEDS, especially the Magnesium (Mg+) Ions from the Plant Chlorophyll, to Properly Function, and will give you a CALM, GENTLE ENERGY, like a Cup of Japanese GREEN TEA, for the Rest of your Day. You become Mentally Alert, but Body Relaxed, which is why Buddhist Monks use it to Meditate. RINSE then REPEAT, DAILY. Welcome to your New Life. 5-STARS, and suggest you try it too.
