So many questions, sheesh. ;)
Inquiring minds wanna know :D
I’m not sure, really don’t know anything about body work except from what I recently learned from @Rocketman and to remove and replace parts! As for the wheels, I have no idea who made these, so it’s been a mission trying to find the meter caps. But not going to give up until I find out!

I was just wondering because your roof was pretty bad. Although, being it's the roof it's not like anyone is really gonna look up there and notice any ****** bodywork or paint.
I'm sure if you post a close up pic of a rim someone might recognize the brand or name of it.

Recorded a cold start video, post-BBP tune:



Now I REALLY want my cam... [emoji16][emoji631]

Trying to decide if I want to replace heads or not.. I was planning to get a BTR or TSP stage 2 cam, but don’t want to lose any low end tq. And I think any stage 2 has that consequence even a slight loss. [emoji53] so either getting springs and cam, or a whole head set. Eventually I’d like to SC her, but I need to get a plan together for the pieces I need to assemble.

Have the combustion chambers brought down to around 63cc and run thinner gaskets and you'll regain any TQ lost from the cam. You'll gain power across the board, not just down low. I like 10.5:1 CR as a minimum. Also, while the heads are off, have the bowls blended in. Smoothing the casting in the runners and refining the hump around the valve guide are easy but effective little mods.

If you find a deal on some, get 243 or 799 heads and do all of the above. You'll be starting with a better design and larger intake valve to complement a cam.

If you know for sure you'll be boosting, then disregard raising the CR.

Yes it was! Don’t mind the questions, I just don’t like not having answers! I didn’t pay to have it painted, so I know it’s not. Decided to wait to paint one time which will likely be after I get a lot more done to it first. Waiting on rotors to do NNBS upgrade, should be here within next couple days. I’ve got to get a front bumper to replace the one that’s one there now. I can tell it’s been in an accident and they did a piss poor job when they put it back together. I’ll take a pic of the front end tomorrow and you can see for yourself.

Hopefully the roof is sealed well, being it isn't painted. Don't want it rusting through the repair and bondo.

I hope it was at least primered, Bondo soaks up water if left uncovered.

Wondering if I should get that dupli-color paint in a can and paint it? Did buy some to do the rear Esky appliqués and the rear window trim. I did also get some clear coat to paint over that as well!

Should help. Do a few coats. I can't believe the body shop let you go without saying what could happen to the bondo when there's long term exposure to water or moisture.

Sounds like you have a small cam in there already! Sounds good. Stock exhaust?
Thanks Tony! It’s got the ARH Longtubes with cats, and stock pipes, but with muffler replaced with an 18” magnaflow, and deleted resonator. Actually, I was suppose to tell @iamdub the rpm where I get the most drone with this exhaust, to look into a Helmholtz resonator IIRC. So, iamdub, it’s worst at 2k, which I suspect is quite common.

In other news : Dude on Instagram sold his rare clear tail lights. $20 a ticket with 1500 raffle spots. So basically sold them for $3k lol. But the winner got them for $20 (might have had a couple spots but still these go for 400 all day used) .
Should’ve did that with my clear corners:hmm:

Got my truck back from body shop that was fixing the holes that were in the roof. Started installing Esky roof rack!

Also pictured are the wheels that I’m looking to get center caps for.

usually wheels have the model number stamped on the backside, take a wheel off and write down the numbers off the backside, one set will probably be the size, etc but one should be a model number then maybe google that +wheel and maybe you will get lucky.

I’ll take a look tomorrow. Thanks for this great information! Will most likely do it after I go to the post office in the morning and tell them a thing or three about themselves!

Had to replace the driver side view mirror glass after breaking it backing out of my new garage. Went OEM since it’s got the auto dimming etc. The first one I got was defective and looked like a fun house mirror. The second one was perfect. I can guarantee that won’t happen again.
