- G Force has developed a frame extension, GF-FE100 to duplicate the longer frame on these early generation vehicles. The RCG-4L80K is pre-packaged with the frame extension.
- The primary frame change on the 1978-1988 generation of GM G-Body vehicles begins with 1984 models and the implementation of the 2004R transmission which required positioning the crossmember further to the rear of the vehicle. This is evidenced by two sets of frame holes for the crossmember on the driver side of the vehicle.
- Note: Some 1983 Hurst Olds are known to have the 2004R transmission and thus the longer frame rail which does not require the GF-FE100 frame extension that is included in this Kit. Some 1984 El Caminos retained the early frames and do require an GF-FE100 frame extension to run this crossmember.

Doesn’t last long
Color: DR HAZELNUT BROWN, Color: DR HAZELNUT BROWN
I love a synthetic wavy wig but this one didn’t even last the entire weekend like most do. Look very cute the first day but after that it just didn’t do what I needed it to do any

All eyes on you!
Color: DR2GDNHN, Color: DR2GDNHN
I didn't love this wig straight out of the box but after trimming the wig to frame my face and brushing out the curls (I love big hair), I absolutely fell in love with this unit. I've received so many compliments. Wig does tangle but after applying product the curl pattern returns. Will definitely purchase again!

Great quality product!
Color: Caviar PDRN
I really like these! They have just the right amount of moisture and depuff my eyes perfectly! My eyes are very sensitive and I did not have any issues. Light to no fragrance and easy to use. Compared to other brands, the value is great! Recommend these!

BioYessssssss
Color: Caviar PDRN, Color: Caviar PDRN
I was honestly impressed after just one use of the Biodance Caviar PDRN Eye Patches. The difference in my under-eye area was noticeable almost immediately—my skin looked brighter, smoother, and more refreshed, like I had actually gotten a full night of sleep. It gave my eyes that well-rested, radiant look that usually takes multiple products to achieve.
What really sets these patches apart is how well they stay in place. Unlike so many other eye patches that constantly slide down and need readjusting, these adhere perfectly and stay put the entire time. I can go about my routine without worrying about them slipping off. Between the instant brightening effect and the secure fit, these have quickly become a standout in my skincare routine.

These are a winner!
Color: Caviar PDRN
These are some of the best under eye masks! I have friend about 35 different ones and these are slightly textured so they do not slip as much as a lot of the other ones! They are thin and very hydrating!!
