Does anyone make a 12:00 timing tab for SBC

I'm building a 350 and the 6 3/4" balancer I have shows top dead center at about 12 or 12:30 or so when I eye ball it. The stock timing cover has a timing tab welded up top, but it's in bad shape so I purchased a after market cover. I also bought an after market timing tab that was listed for a 6 3/4" balancer, but it attaches over at about the 2:30, so it's way off. I thought about using timing tape and locating it at the new tab. But with an AC compressor and power steering attached on that side I'm not sure I would be able to see it once everything mounted up.

Does anyone make an after market timing for balancers that have their top dead center mark up top? Seems to be a lot of engines set up that way.

Helpful info

Go to Google and type in Professional Products,when the list pops up click on the harmonic balancer,it will take you to a PDF file.On the right side of the text under notes it explains the SBC timing marks and the tabs you can use.The balancers they have available come with both sets of marks and are much easier to read than a stocker and almost the same price.

All it tells me is they have a balancer that includes a mark for 12:00. It doesn't mention any tab that will work with the stock balancer. I was hoping there was a solution that didn't cost $150.

I can't believe there isn't anything out there for the huge number of small block chevys made from 84-95.

A stock timing cover from around 1979+

And actually, I have found these easier to read than the 2:00 timing tabs.
Point the light straight down near the water pump and you have it.

OK,I will make it a little easier and it won't cost $150 either.Click on www.summitracing.com and at the upper left in search put this part number in,PFS-80000 .Now you already have an aftermarket pointer so you are getting closer,1984-95 350 Chevys have the 12 o'clock pointer this balancer has both early and late marks so when you install it on your new timing cover TDC will be around 3 O'clock with the pointer you have.Could be worse, 302 aka SBF Fords had 3 different timing marks.

Cadillacs have 6 different combinations of tabs to dampers!

I would first DETERMINE TDC then MAKE A TIMING TAPE.

Permanently mark the damper at TDC, aligned to the timing tab you have, or which ever one you want to use. Lay the timing tape on, aligned to the "new" TDC and you're good to go.

If no tuning for total advance is needed, or you have a dial back timing light, skip the tape.
