A very open question and my reply is very late, hopefully nobody lost fingers if you’ve got it on. For the purpose of a reply I’ll assume that it’s a hard top. There’s two rubber seals, one along the front windscreen and the other around the rear tub. If you don’t have the latter don’t put it on. It’s not expensive but it’s essential otherwise it’s leak like a sieve. Hopefully you’ve got all the corner and side bolts? Again if you don’t you need to order all these party. It’ll take thre people to mount the hard top but you have to have all the fixings. If you don’t have these, can be ordered online. You need a workshop manual.
