trying to save money.... lol

I was wondering if anyone has weighed their 1992 Chevy Silverado 1500 V6 manual trans and calculated the corner weight and unsprung weight/ with a long travel kit..... I'm trying to save money in one sense but I also don't have the time due to my work schedule to get my truck weighed and figure the numbers..... any references are helpful I'm not looking for exact just close estimates.... trying to figure a decent spring rate to start with for the coil-overs....
What is everyone's thought on btf fabrication and lsk suspension for the 88-98 Chevy 1500 long travel kit.... In means of price for quality I'm just now getting my feet wet and I'm wanting to get a good reliable kit for my OBS Silverado
