Laysons patch panel

Check with Classic Industries as they usually have them. They run sales a few times a year.

Laysons has a reputation for taking money on parts they don't have in stock and stringing people along. Many, many complaints about that.
Personally, I bought 68 cuda tail light bezels from them and was sent scratched and dinged up show displays in 1966 cuda TL boxes. l complained saying I didn't want scratch and dent specials at full price. I returned them and was out $85 for restocking and shipping. I saved all the emails where they flat out lied to me.
Another Barracuda Buddy bought gen 2 cuda tail lights from them and on his first ride, one came apart, fell off the car, and was run over by a following car. They did not stand by their POS product so he got screwed too.
I haven't bought a cotter pin from them since.
