mehere Posted February 2, 2018 Report Share Posted February 2, 2018 Also quite possible that they found a "stash" of alloy ones under a bench somewhere and used those up, later on with the 5... ?? Quote Link to post Share on other sites
stuart Posted February 2, 2018 Report Share Posted February 2, 2018 The rear sections were mostly fitted to TR4`s when new and all of them had the forward stud fitted right to the end of production but deleted on fitting to 4a/5`s The Alloy roof was still an option through 4a production I believe and was marketed as a "Ladies top" as much lighter to remove/fit. If you still have an original rear window fitted then you can check its manufacture date by reading the dots on the Triplex marking. http://www.bobine.nl/turner/01-general-information/triplex-glass-manufacturing-date-codes/ Stuart.

Tom Fremont Posted February 2, 2018 Report Share Posted February 2, 2018 The alloy lids kept the weight of the hardtop within 7-9 lbs of the soft top, all told, glass and all. As noted above,they're very remove/refit friendly weight-wise. You can have fun with polishing them bare, too . The moorings rip out on them though, especially the rear ones, and unless this is well reinforced is a critical defect. All (3) of those I restored had this addressed. Since they don't rust the survival rates are far better than the steel ones, which bereft of any coating whatsoever rust at the seams where condensation settles. Dry state lids are the best bet in steel, but just imagine how many new car buyers in those warm, sunny places would go for that option . Cheers, Tom Quote Link to post Share on other sites
Dave Ashworth Posted February 7, 2018 Report Share Posted February 7, 2018 Like Stuart, I have a fibreglass backlight on my TR4, it was on there when I bought the car and didn't notice it was fibreglass until two years later when someone pointed out the profile was different. They are good. Cheers. Dave. Quote Link to post Share on other sites
