how to remove injectors

[Tymk1]

So I recently put a 1.8 8v in my mk1 anda owner of the motor I assume a while ago removed the fuel injection this motor was originally out of an audi. Anyway my issue is the bolts used to block injectors seem like the injectors where welded shut so there is a 13mm nut with the end welded over and a 12mm bolt sleave so it goes in the hole where the injectors used to go and the nut goes over to cap it off but it leaks I can remove the nut easy but as for the bolt it's a mission it just seems to spin will not pull out either, does anyone know what the original injectors would have been held in with?
Or have any other ideas? How to remove them so I can replace with a bolt that fits.

Thanks in advance.

Standard k-jet injectors are just pushed into the insert, which may be brass or plasticy looking.

K-Jetronic?

The original injectors were just held in by their o-rings.

They should pull straight out. There's a tool available to assist.
