Sorry you had to go through that guys. But if either of you have any pics of the bolts in question, or more details of the exact reason the one bolt/pulley is not compatible, we'd like to see/hear them.
Are the threads different? Does it put the pulley out of alignment with the belt? What exactly does it do that won't let it work properly?
If you have some, send any info, pics or suggestions to
sales@wildhorses4x4.com (attn: PaulB if you like) and we'll add the notes. Or, if it's a simple change to our bracket that can be made to take that into account, that would be an even better result.
