Hub bore size on the snowflake?

Hey! What is the hub bore size on the snowflake? I have found the wheel is 16x7 +32, but I’m unsure if the offset is correct. Can’t find any info on the hub bore size. Thanks for any info!

In case I or anyone else needs to search for this information in the future. 1988 Ford Thunderbird Turbo Coupe hub bore size is 63.4mm Snowflake wheel is 16x7 +31.8mm offset 4x108 mm or 4x4.25 in.

17x9 +18 wheels will fit without any modification BUT the front wheels slightly stick out from under the fenders (15mm or so), but the stock suspension prevents the tires from rubbing. Also, the rear wheels still have some room to grow. 17x9 +0 offset would be a perfect fit in the back and would be flush to the fender without rubbing or poking.
