I've been working out since I was 13 and I am now 47 .Love it never gonna stop. I'm 5'5" and weigh in at 188 lbs. 17 1/2" arms .Only 31" waist so no Im not a fatty .lol .
I have only had the Daystar spacer ,it a 2 piece half goes on top of the plate and the other half under the plate .Any how my thought is if the whole block goes between the spring and the plate it would compress the spring more and make for a stiffer ride .Just my 2 cents.
I have a 86 runner right now that the power steering pump makes a hell of a whirring noise for 3 or 4 min. till it warms up. It's fine after that ,no noise when turning. I've had speedo cable make noise before it was more of a grinding noise than a whirring.
The black runner has a Dana 44 front axle out of a 76 wagoner .The rear axle is Toyota it has 5.29 gears and a locker.The rear leaf springs are 63"long Chevy springs. The only thing different under the hood is a K&N filter.Here is a pic of the inside .Check out the NRG steering wheel.
