Lincoln Park, Brownstown INDIANA SUPER STOCK question

[fuzzyfoamrace]

Can somebody please clarify the rules regarding metric chassis. I'm looking at two different builders and one has stock clip just past rear spring pocket. The other uses front clip to fire wall only. His rear mounts are factory location but weled to tube chassis. Are both ways legal? Been out of racing for too long. Any help and chassis builders of these would be awesome. I have only looked at pictures on facebook sites for CY CHASSIS and GUMM.
