340 starter mini question

I have a mini starter on my 340 with Doug headers 727 Trans. and I bolted it up like the old gear reduction starter. I did make a heat shield for it because the header is close. If I find the picture I will post.
I did find out my mini starter is a Chrysler part number 53005984 it came on the car. Works great, not sure what its off of but I will ask my parts guy tomorrow. Picture of shield below.
