Some of those prices are decent, but you can get sill plates for less than $100 a set, and trunk weatherstripping is about $25 a roll. Curious to see what else this person has...
The B-59-60 sill plate repros are not exact tho- they feature etched texture rather than stamped. At least the repros I bought do.
The ones I bought looked just like the originals I pulled off. There are a bunch of different repros, so you need to be careful.
