I modded my 74 male buckles to fit 73 female buckles. Just a little grinding off of each edge made them fit. The 74's I have had an extra stepped edge and wouldn't go all the way in. Mine are the chrome buckles, silver square inserts. Not trying to threadjack, just giving you some options....
I'm still working out whether or not I'll be able to make it. What would be the best day to go to see as many Mavericks as possible? Also if I do make it craig do you have any more Chilton manuals? And what happened to that speaker box template?
Saturday is always the highest turnout. I always go Thursday so I can spend 2 days going through the vendors, then try to stay with the show cars Saturday.
