Greetings to FABO. Hope everyone is well. Many questions were answered on my last two threads but one. What is the minimum back spacing allowed on 68 Barracuda with 73+ disc brake conversion. Received many answers as to what would fit but different wheel and tire combinations were involved without much back spacing information or if provided; did not fit my wheel availability. Thought I would take a different approach. The following are my front wheel options. Question 1: Will I have clearance issues with 205/60-15 on either 15X6 3.25in BS, 15X6 3.75in BS, or 15X7 4in BS. Question 2: Will I have clearance issues with 205/70-14 on either 14X5.5 3.75in BS or 14X6 4in BS. Thanks.
