Is there a flat rate charged to install shocks?

Do shops charge hourly or flat rate to install shocks?I am driving for a guy right now and he bought the shocks, i installed , i was wonder ing how to charge.i usually charge 65 an hour,but i have 2 hours travel time to the shop at home included,3 hours work time, but i am going to want to get pay for drive time too.

 

I had to heat each one up and zip off with impact.I left the yard a 2pm and returned the truck at 7pm.next time keep track of my time working on it i guess

 

LOL kinda had a mix,there all hydraulic,I called all over on friday in the mpls area cuz i needed new shocks i am running an old old fright shaker 1994, no cab air ride,lucky it has air suspension,I started 3 weeks ago,for this guy who said he runs older stuff, BUT it is TAKEN CARE OF, not,anyway i could not stand no more it beat you pretty bad all day long,to the point i got head aches and the noise oh my.and i had not had a sore back in 3 year till i ran that junk,but guys say hold out MIke he is getting truck this summer.He just bought a company with 238 truck nice KW's so i will stick it out now that i can ride this baby and stay on,the good it is not governed and will go 85 if i want,I haul container,and paid percentage.so anyway i called the local car quest in my town cuz they do a lot of big truck part and they had the 2 steers,and one drive,i called freight shaker and several other part places and no one had them all,i found 3 drive at Boyer ford in mpls they charges 400.09 for 3 drives,I was going to hand the boss a jar of grease,and the car quest was 200.00 for 3,they are all Gabriel.And i tell you what it is about 90% better ride,next i will have to fix what ever is lose un the tranny i think a mount is broken unless it is a mount for the power plant,cuz when iam loaded and it torque the clutch pedal moves a bit along with the stick.
Truckon as far as 25 per hour ,it would be nice but iam out to make money not be nice,thats how i lost my business and am driving truck again,i had a repair business,but i been working on cars an trucks and equipment most my life,so i bill him thou my former business with my fed an state tax id.And some shops around her charge the lowest 65.00 some do 120.00.he said i am
him a big favor so he must been ok with my last bill
