Fitting a new seat back foam can be difficult. For one thing a new foam piece will appear to be quite large compared to the old one. Deterioration and ageing make the old foam shrink substantially!
Extra time and effort taken in forming the seat back foam & backboard together will be rewarded with easier assembly.
Fitting the seat back upholstery can be difficult. We recommend having a headrest shoved into its hole while pulling the back upholstery down. It provides a good reference point for fitting.
When pulling the side flutes down, do it carefully. Excessive “yanking” on the back flap will tear out the stitching! Having the seat back upholstery fairly warm will allow it stretch into place easier.
Also be wary of the seat adjuster while sliding the upholstery over it as damage is easily caused.
If you pay heed to these pointers you should have limited troubles in doing the job. Should you not feel confident in attempting this job, take your seats and the upholstery kit to an automotive upholstery shop. From what we’ve heard, most shops will do this job for a couple hundred bucks.
In either case, newly upholstered seats will greatly add to the enjoyment of your MGB as well as increase its resale value.
