My friend of mine who's into Vintage Harleys buys his cloth wiring from YNZ Yesterday Parts In Redlands, Ca. Phone 909-798-1498 and e-mail Support@YnZYesterdaysParts.com.
Another source up here in New England is " Tom's Engine Barn" Located in Bradford Mass. # 978- 376- 5540 tom@enginebarn.com wwwenginebarn.com Recommended by a restorer friend of mine. Good luck.
I found a complete wiring kit for a '50s Ford on sale at Vintage Ford. Not cheap but on sale about the same as a regular kit. It has all I'll need for my '26 Chevy roadster and technically it's not a Ford part. It's just a bunch if cool wire. It is good quality new plastic insulated wire with the cloth over the top. Each circuit is color coded & the right gauge. It will be fun when I get to that stage.
Yes, Sacramento Vintage Ford. I got it in 2019 and was on sale for some reason. Maybe it was a special run? Looking at it and thinking how it will look & work I think it is worth the cost. I can post pictures if you are interested. It is a very complete kit. Item # 17500 Bin: 53-185 Description: Vintage hot rod wiring kit Price: $359.95
Have you checked with these guys? I buy from them all the time. They also have Raja clips and dist cap ends. They are a full service auto electric Co. Rhode Island Wiring Service
I should have added once your in the sight click on supplies on the bottom of the drop down menu. This is what you will find under plug wires.
I just started buying from Rick at Noble. His stuff is really nice. I bought some Stromberg 97 bowl covers.
