Since many Chrysler enthusiasts use the B1 head or aftermarket valve covers, these Pro-Billet Chrysler Distributors have been designed with a small diameter housing. This allows the distributors to fit tight block and head combinations. For accurate timing, a high output magnetic pick-up is used that plugs directly into your MSD Ignition Control. There is an easy-to-adjust mechanical advance mounted on top of each distributor and is easily tuned with an assortment of supplied advance stop bushings and advance springs.

Excellent Inserts. Great price point.
Color: White, Size: 12x20 Inch
I purchased the 20x20 first and loved them so much, I purchased these the next day. They come vacuum sealed so please do be careful opening them. It takes a little time and patience. These fluff up so nicely. I manipulated by hand a bit then into the dryer with wool dryer balls on medium heat for about 20 minutes. They are odor free which is a big plus for me and the quality is there for the price. I can't use feather inserts for anything so these are the next best I've found at this price point. I will be purchasing more and I do recommend.

Fluffy and Supportive Pillow Inserts
Color: White, Size: 12x20 Inch, Color: White, Size: 12x20 Inch
I used these pillow inserts for my couch cushions, and they’ve worked out really well. They give my throw pillows a nice full look without being too stiff or flat, which makes the couch feel more put together and comfortable.
Filling quantity: They’re nicely filled and give good shape without feeling overstuffed.
Durability: They seem well-made and hold their shape well even after daily use.
Color: Clean, bright white that works well with different pillow covers.
Appearance: They make my decorative pillows look fluffy and full, giving the couch a more finished look overall.

Exactly what I was looking for
Color: White, Size: 26x26 Inch
I bought these to fill some euro pillow covers and they worked out really well. They come vacuum packed, so at first they look flat, but once you open them and give them a little time, they fluff up nicely.
They are soft but still have enough structure to hold their shape on a bed or couch, which is exactly what I was looking for. Not overly firm, but not limp either. They give that full, styled look without feeling stiff.
The size is true to 26x26 and fills the covers well without looking saggy. I like that they don’t feel hollow like some cheaper inserts can.
Quality feels good for the price. They are not luxury pillows, but definitely a solid option for decorative use and they hold up well.
Overall, really happy with them and would buy again for other rooms.

Great little sprayer
Size: 1-Gallon
This thing works really well. My only complaint is that you can't really get a tight cone on the mist setting. I wanted to be a little more precise, but it still got the job done. I would recommend this more for lawn treatments over bug spray (which is what I used it for), just because of the wide dispersal cone (especially indoors). However, it still works just fine, and gives a lot of coverage in a short amount of time. It does shoot a very precise stream out, but it's way too much liquid at once in my opinion. If you're wanting precision, you'll need to look elsewhere. As for the value, it's well worth it.
