These are the narrowest seats available.
https://www.corbeau-seats.com/product/sportsman-reclining-sport-seat/They may just fit but it’s very marginal. With no runners they already look quite tall and add another 30-40mm in height and I’m concerned I’ll be sitting too high
Also they are vinyl not leather. Piping to match my car is £50 per seat extra binging to total to approx £1000! I’d risk it at half that but not at that price
