One Piece Window Conversion

[lkt1954]

I'm putting a one piece window kit in my 69 C10. So far here is what my research has found:
1) Two kits- Brother's Kit and One Piece Products.
2) Most post on here that I have found about these products are old (5+ years).
3) Both products seem to according to various post have both installation/function issues.
4) Numerous post on staying with vent windows.

With all that said I have always liked the look of the one piece windows and hate vent windows.

My question here has anyone in recent years (last couple of years) installed either product and what are your thoughts? I would think over time these products would have been improved to resolve some of the issues I have read about in various threads.

I'm leaning toward the One Piece Products due to the fact I'm not thrilled with the filler piece on Brother's kit. However the price difference makes on think hard about the two kits.

Any thought or comments on recent installations/improvements on either product?

Thanks
