I am not totaly upto speed on grills other than that looks like a 67/8 grill to me. so about right for your car..
the bars are easy to make it's just the time and access to the machine in the first place. I keep meaning to buy a lathe/mill Hobby one as I used to be a Machinest when I was a wee boy..

Same I don't have access to our old machine shop ( it's all gone now and the building ) i was the CNC guy. We used to have a laser cutter that was great for side line jobs.. draw a picture out on the paper the laser used to follow it and cut the steel out upto 2" thick
I used to make Small hands as paper weights for fun for the office when I was just using up material.
Miss those days we could almost make anything. We had a Russain 30Ft bed lathe one of the biggest in the South. I used to do some big stuff on that till 11 at night when a machine went down. Some times work though the night to get stuff made and out the doro the next day. Most of what I made was big heavy stuff crane's needed for every thing even to put the billet in the chuck needed a lift. One job I did on site needed Europes biggest Crane to come to the UK to lift it off and then alow me to take out the old bearing and gear and fit the new one I made. Then that was £35K to turn up for the day!!! so if the gear was wrong I was in the SHI&&. Had it all back in in 30 mins and sent the crane on it's way ..... and it's 4 trucks that came with it!!! took then 2-3 hrs just to set it up..
Some how now I make curtains and blinds and design rooms for people not sure how heavy work like I did to fabric worked out but it's sure cleaner
