yes i make fibre glass parts for the ford pintos. i have side louvers rear louvers front spoilers hoods, fenders . i designed these up for my pinto all the parts are custom made. i have been building fibre glass parts for 15 years. you could check on ebay i have a set of side louvers listed now, see the quality for your self. the rear louvers will be listed in a week to two let me know if you like the thanx. :look:

never seen them for an all glass, there were lots of different options in the past for the reg-hatch but you'll only find them if somebody has them used and willing to sell (pretty rare) the side 1/4 windows - there was someone making and selling on Ebay a few years ago, hasn't been seen/heard from for some time...

in a nut shell - extreamly hard to find/no easy answer

I picked up an NOS in the box set of Lift Louvers for a steel hatch off Ebay over a year ago & paid $425 shipped to get them. I considered them a bargain at that price.
 
There's a kid on here that inherited his dads Rallye & he has louvers on the all glass hatch so they definitely made some but I've never seen a set for sale & I look daily.
