Common way to swap to a different lug pattern involves a wheel spacer lug adapter, which is probably a minimum of ~1" thickness, so keep that in mind when looking into wheels
Thanks I dunno where you were looking but I just Googled it and saw many adapters for going either direction between 5 and 4 lugs
I'm going to throw this out there as well. Could allways fill and drill for different lug patterns. Will be expensive but can be safer done right.
I have a 77 SR5 pickup for the individuals running 17"x9.5" or 18"x9.5" square setup what offset are you running I read a old post on a different site and guy said he was running 17"x9.5" -10 offset and they were tucked and on a 4"/3" drop I am currently at stock hight but what are you all running in that range that is tucked or at least clears the wheel well. Pictures would be awesome as well if possible
Don't forget about hub bore sizing. If the rim's hub bore is too small, adapters will be needed to push out the rim or you can have the hub bored out to fit
