Replacement for rope seal in a 283?

[Adger Smith]

I have used the right thickness Plastic tiewrap/ziptie instead of the wire. Takes a little trimming and fitting. The tiewrap/ziptie also works well when I align bore/hone a 400 block and remove seal lip material. Think of it as just filler material to get the seal to crush properly. You can get it crushed too much and it will leak.
