1) i have a private key which begins with K and is 49 Characters long base58
2) i have a private key which begins with K and is 54 Characters long base58
PS: If i use the the script on here and use this in github https://pastebin.com/S8WARrRn? will it work or do i have to use it on pastebin to run the script ?

no it won't work because it is hard-coded for a special case and none of the settings match your issue.
- only has a fixed number of missing characters: 5
- is an uncompressed private key (starting with 5)
- you know the location of missing characters

your private keys are compressed that start with K and their length should have been 52. and you don't seem to know the location of the missing characters.
now are you sure what you have are actually private keys? how did you lose the rest of the characters? for example if it is from the end then recovering it is going to be trivial as it would take a fraction of a second.

p.s. if my calculation is right you have to check 22.94 billion keys if you miss 3 characters and don't know their location.

Thanks is there a tool i can use to recover ? as i must have missed a few characters off or could someone help me via private message as i do not want to disclose it on here !!
