Hello,
I have for sale few bolt kits for soft top frame. These have m8x1,25 thread and are made to fit 230SL early frame. Check your old bold thread. No returns accepted therefore! I have seen some bolts m8x1mm! M8x1 can be recut to 88x1,25 as I have done on one frame. Use Loctite thread locker (the highest rate) to secure them!
I guess most of them are used also for late frame as on 250 and 280. Check pics for details.
I suggest to change brass inserts where main/long bolts go into!
Price 129,- EUR incl. shipping.
