As far as the soft top install... I had some trouble with the catches at the front... The back of the front bulkhead/bow? that they fasten to was on too much of a slope... the catches needed to be more 'vertical' to fit the slots in the bracket on the windshield frame.
I had 2 top frames to work with on this install...the one that was in the car with a replacement ( but old ) top and one from an Alpine SV that I got from a parts car... luckily there were enough good parts between them to make one good frame. I used the front piece from the Tiger and it had the catches bolted directly to it so I assumed that was correct and manage to force the catches in with the screws backed off but never did resolve it...
Yesterday, I took the catches off the old Alpine and lo and behold there were these nice little cast aluminum wedges behind them. I'm sure they are not home made but either way, they are exactly what I needed to correct the alignment problem on the catches !
