- We recommend a polyurethane transmission mount. The GMTM is sold separately.
- If you have a 78-83 vehicle G Force has developed a frame extension, GF-FE100 to duplicate the factory driver side longer frame rail. The frame extension is sold separately, or can be purchased in a kit, RCG-4L80K, which includes both the crossmember and 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.

Very compressive
Size: Large, Color: Pink
Super compressive for girls clothes. Great dress though, my daughter didn't love the feel of the super tight athletic wear feel though.

Adorable but runs small
Size: Medium, Color: Black/Ivory, Size: Medium, Color: Black/Ivory
These are the cutest shirts- cotton, soft, thick- good quality but SMALL. Returned because of size and ordered a bigger size. I added a picture for reference- the other is a cotton 7-8 from Disney - I feel like the M /8 amazon was more a 6. I definitely recommend these shirts though just size up at least one size.

Gift for granddaughter
Size: Large, Color: Mauve/Butterflies
My granddaughter likes these tops. They are sturdy, comfortable and soft. She loves the ruffles on the shoulder. They were reasonably priced and I feel they will last. Look good after a number of washes.
