1935 cabriolet vs convertible sedan front seat back size

Thanks Curt I'll try them

Thanks, but the measurement i need is the cabriolet front seat, seat back

Contact Snyders, they make them new.

I can provide a measuremnet for the rumble seat back spring, if needed

Thanks Curt, but I have a narrower back seat back from phaeton thats identified and an even narrower rumble seat back. The 2 front seat backs are only about an 1 1/2" difference. As good as the parts book is I'm surprised it only has broham seats listed.

I believe thw wide one is front and the narrow one is rear.

I've got 2 seat backs (just springs) 1 set is slightly wider.  We're the seat backs the same size?  I couldn't find parts numbers for either one in the parts book or supplement.
