Help choosing sub frame connectors

[WHITE AND RED 69]

I am looking into adding subframe connecters in my 69, but not sure which ones to go with. I dont really want to go with bolt on but I dont want to pull my interior to get weld in ones. What is the best option, should I just suck it up and pull out the carpet. My first choice was the xv connectors, but I saw hotchkis has connectors that bolt to the rear and weld to the front and does not require to mess with the interior. Is there any weakness to that? Anyone have any experience with the hotchkis ones? Thanks

Xv or uscartools are the best ones out there. Pull the carpet and weld them in,you will be far happier with the result.
