Fitting new side window rubber seals

[Gilbern74]

Having dismantled all the side windows in order to replace the old seals with new ones, I purchased new rubber seals from the Club and last night attempted to fit them back on the windows and in chrome frame. Not a chance!
I tried combinations of fitting the seals to the window glass first, then push into the frame. Then putting the seals into the frame, then pushing the window glass into them.
All done with lashings of washing-up liquid to encourage the seal and glass to slide into the frame.

Is there a trick to doing this does anyone (who has attempted this) know?

I'm inclined to go looking for new seals that are about 0.5mm thinner which should be the simpler solution.
Found this selection which I'll try once I've taken the dimensions required for the seal

I am assuming you mean the rear quarter light windows?
I could not find a suitable seal when I replaced mine, the original appeared just to be a strip of flat rubber such as you would get by slicing an inner tube length wise.
I finally decided to fill the groove completely with silicone sealer and slide the glass into it, this worked and has the benefit of filling the corners where the glass does not fit but it is extremely (understatement!) messy. I left it to set and trimmed off the edges.
Incidentally one should NEVER use washing -up liquid to fit rubbers as it contains a large amount of salt which we all know attacks metal but it also attacks rubber.

When I did this on my Gordon-Keeble, I found the same issue, bought allsorts of lengths of rubber seal, but all was either too tight or too loose.

I had great success with neoprene foam tape, loads of thicknesses and widths on ebay, not expensive. Select a thickness that get plenty of compression when installed, I stuck it to the glass, then shoved it into the frame. Final trim with a sharp knife.

Thanks guys. Rather than using washing up liquid I have read that a dose of talc works really well to slide the rubbers + glass in so I might try that.
I have ordered a couple of sample strips online from RubberStock and will let you know how they fit.
Yes the original seals were just wrapped rubber - I might go and use the same method combined with added silicone sealant, if I cannot find a suitable moulded seal.

For the record, I had my digital callipers out to get some measurements of the glass/frame/rubber as follows:

Glass -
Width: 5.1mm

Frame -
Channel depth: 10mm
Channel internal width: 7.3mm

Rubber seal from GOC:
External width: 7.7mm
Internal width: 5mm

Silicon spray should give you the slipperiness you need.
