i already have fiberglass insulation between the joists that doesn't come up to the top of the joistsi'm thinking of laying batts down on top of the joists, going the other waywill that gap be ok? any suggestions?
There are no aftermarket T-tops made for your car.
This is a really bad idea It will not be cheap, you'd have to find some already existing T top panels that would be appropriate for the car, and then you would need someone with the skills and know how to modify the structure of your Mustang to compensate for the structural losses that will occur when the roof is cut - it's not just a matter of cutting holes and putting new panels in and you're doneOne of your biggest problems will be finding someone to do the engineering work, because it's a custom it will be more expensive than if there were some shop already doing this In addition you have a brand new car with a warranty - since this modification would compromise the structural integrity of the vehicle some parts of your warranty might be void because of this - I'm not sure about exactly what but this is something to consider The reason why Mustangs and Camaros aren't offered with t-tops anymore is simple - they are offered as true convertiblesIf you think about it, other than the C3 Corvette which was offered as a t-top back in 68 on, most of the cars that used to be offered with the t-top option were not available as convertibles - 70-80's Mustangs, Camaros, Firebirds, 300ZX, etc So my advice is skip this idea and if you really want to let the sunshine in, get a Mustang convertible instead, it's much nicer than a t top.
I work for an Insulation company and the best way is to have loose fill fiberglass insulation blown over top of the old by a contractor ,That way it getis in all the cracks.Also todays code for insulation depending where you live is an R38 about 14 of toal insulation and should run you about 50-65 cents per square foot compared to buying rolls and doing it yourselfat about $1-$2 a square foot
