Trying to locate retro football jerseys

I'm trying to locate some retro football jerseys. A few months ago, I saw some old school '97, '98 and '99 era Manchester United jerseys at MBK but they did not have a lot of choices in terms of sizing (I wear Thai XL). What I would like to know is where I could specifically go in Bangkok to find retro, replica jerseys in abundance. I don't want used, vintage stuff but recreations of replicas. Since they sell a few of these at MBK from time to time, I figured it'd be more beneficial for me to check out the actual source. I've been to Chatuchak many times but they mostly sell used and overpriced vintage jerseys. I'm trying to locate recreations of these older jerseys similar to the ones I saw at MBK a while ago. I've tried to research this quite a bit and I came across some pretty old posts regarding shops around the National Stadium. However, I have also read that the inner soi where they used to sell these jerseys aren't around anymore. I'd really appreciate any help. Thank you in advance!
