Will stock 4cyl 10 hole wheels fit on a 5.0L? Was there any difference in the axel hole size in the middle of the rim?
thanks

 

Do you mean these?

These are not 4 cyl wheels the cast aluminum 15" 10 hole where 85 - 86 GT wheels, then 87 - 90 LX 5.0 wheels, then in 91 - 93 they where offered as an optional wheel for 4cyl. And yes they will fit a 91 - 93 GT or LX 5.0.

 

so I assume my 93 4cyl 10 holes will fit an 88 5.0L LX?

 

they should

 

If they are the same as the ones in the old picture of my car yes they are the same wheel.
They will fit ANY 4 lug Fox platform car Mustang, Capri, Thunderbird, Cougar, Fairmont, Zepher, reguardless of engine size. I have even seen them on Mustang II's
