1 AnswerChemistry8 years agoHow much should I spend to restore my 65 Barracuda (V8)?
The car is straight, has no rust and no body filler. Needs new paint, new carpet kit (carpet is faded in rear), seat upholstery (cores are good). Dash is faded and the arm rests need repainting. I want my car to look GOOD but to be driven and enjoyed. This car has all original parts except for a replaced antenna that the people that painted my house broke. I have about 4200 into it already (including the purchase price). Thanks!

3 AnswersLaptops & Notebooks1 decade agoHow long should it take a plumber to install a sink?
I had a plumber install a new sink and faucet. The old sink was already out and the faucet was new. It took him 3.5 hours and I was charged 407.08 ! He was supposed to be coming out to do that and to fix a small leak under each bathroom sink (2)(which he never got to) the lady on the phone told me about 500.00 to do all of it. Did I get totally ripped off?
P.S. it was a self rimming sink (not undermount)

1 AnswerOther - Cars & Transportation1 decade agoWhat color will match my 1965 barracuda dash?
I would like to use some vinyl dye to restore the original color (as close as possible) to the dash in my 65 barracuda. I don't know what color to buy from looking at the charts. The dash is pretty faded so I don't know what it should exactly look like, etc. Does anyone know what spray (any popular brand) dye would match...my interior is gold. My codes are Trm: P4Y and Paint AA1 A. Thanks for any info!
