Tire spacers

I am planning on buying a 1988 Sebring Healey 3000 but the seller wants to get the tires replaced before we complete the sale to avoid any liability since the car has been sitting for 22 years. The other repairs related to the long sit can be handled later and will be worked into the price but I have to wait on this. The mechanic is having issues replacing the tires due to something special regarding spacers in the wheel well or something like that. Does anyone understand what he's talking about and if so do you know where I might find the part(s) needed myself to speed this up?

Thank you.

Not certain how much I can help, but here goes. I assume (we know what that means)
that he is talking about spacers on the brake drums/disks to space the wheel rims and tires out further in the wheel wells.
I am aware of two different type spacers. The wheel rims on the car are likely bolted to either the drums/disks with the spacer between the brake drum and what would be the back of the wheel rim OR the spacer is bolted to the brake drum and then the the spacer has studs that the wheel rim mounts onto. If he as the original wheel rims and tires, have him match as closely as possible the tire size on the car right now.
Another possibility is that the car does not have spacers, but adapters. Adapters are used to convert from one wheel format to another. For example, many of the Mustang rear ends had a 4 lug bolt pattern, but folks wanted to run a 5 lug pattern (more wheel designs options available), so the adapter bolted to the brake drum (with 4 lugs) and the adapter had 5 holes (or more often 5 studs) to mount the 5 hole wheel rims and tires.
In any case regardless of spacers or adapters, there should not be a fitment problem, as long as the new tire "footprint" is not wider than the old one.

It appears that they worked it out but it's good to know for the future. Thanks.
