Wheel spacers or adapters?

I have a pinto with a mustang 2 rear end. I also have mustang turbines that I run on the car. My problem is that the tires sit too far in (too much back spacing?) I do not want to get custom wheels (4 lug 108mm) with my back spacing so I am playing with the idea to either adding spacers or adapter plates. Adapter plates are fairly easy to get (billet aluminum drilled with studs attached) and can be had with my thickness of 1.25 inches. My concern is that I would need to shorten the existing studs to run them and that they are only as good as the material. The other is to replace the wheel studs with longer units (available from summit racing) and just get the billet spacers drilled at my dimensions.

In my mind, the spacer would be better. Am I wrong?

Do the wheels have indents where your studs from the axle would be sticking out?

For something that thick I like the adapter idea better. I run a pair of one inch adapters on the front of my fairlane and didn't need to trim the original wheel studs.

Porsche 924's and early Audi's have 4x108mm bolt patterns and their offset is different, might be an option for you.

Thanks, I will keep an eye out for them.

i have used the 1.25" adapters on 3 cars without having to trim studs. i had to trim studs on 1" ones.

the ebay ones i bought from two different sellers were both very nice and were used on heavy cars that got tossed around corners.
